Addition:
With a mass of 1.02 M☉, Sirius B is estimated at 5 M☉ during its main-sequence.
Formula: T=(M/L)*10k(where k is the percentage of H in mass that can be burnt dring main-sequence)
Roche: r1/A=(0.49q^(2/3))/(0.6q^(2/3)+ln(1+q(^1/3))) (where q=M1/M2)
Sirius A will lose 1.4 M☉ during the Red Giant period.
However, Sirius B is unlikely to transform into a type-1a supernova due to its distance to Sirius A.
The key uncertainties are the speed at which mass is lost from the giant Sirius A, whether the material that lands on the white dwarf explodes on contact, and whether enough mass can be collected by the white dwarf to get close to the Chandrasekhar limit.
In order to explode as a supernova, the white dwarf must increase its mass to close to 1.4 times the mass of the Sun, known as the Chandrasekhar limit. It seems unlikely that it will be able to do this unless the wind from the AGB star is even slower than expected, especially as the orbit of the two stars will widen(oops I forgot) as mass escapes from the system as a whole. Even if the white dwarf were to capture this much mass. --astronomy.com/...

@@laniakea3393 it's not easy, you need to learn physics first and a crap ton of math.
After that you have to research on a topic of interest.

Sirius is a comedy show about someone who likes to live fast and spontaneously living with someone calm and snarky, making for the perfect foil.
Reminds me of couple in ww1...her husband died young on war while she live peacefully long till her death at 70s
You know, I looked back through videos, and I realized something. It so happens to be that your first star(s) otherwise known as this exact video, is the first time the stars are included by themselves. With no planets along with them. This so happens to be on the same date of when my video of this similar format came out. Which was just the future of Sol.
It makes me wonder... Are you me? Or am I you?
*Watching your videos fills me with determination*
Oh look a fellow Undertale fan
Woah are u the biggest asteroid
@@PBR--mg1xt WRONG.
Asteroids are potatos, and they tend to lack water. I'm actually composed of 25% water, making me more like a comet.
I have a hydrostatic equilibrium, which asteroids don't have, like Eros and several other asteroids. This means I have a spherical shape.
I have layers within my geosphere, which typical asteroids lack, with Vesta as an exception.
I even have an atmosphere, which asteroids are unable to retain.
This is why dwarf planets are unable to be considered asteroids, comets, and other non-dwarfic objects.
Wdym your the biggest asteroid
In the asteroid belt, also i need hydrogen
@@PBR--mg1xt NASA literally calls me a dwarf planet. I'm just not fitting for the catagory. Funny thing is that when DAWN arrived, it also carried what you called me before; an asteroid.
It seems to be this trend when the actual classifications are ruled out about everybody's opinions. Newsflash: Opinions do not decide an objects designation.
So yes, Pluto is a dwarf planet. Not a planet.
"let's collide"
"hell yeah"
I WASN'T EXPECTING THAT LMAOO
The stars chatting about what's happenning to them is so funny, make more like these
Love how Sirius A is like a mom and Sirius B is like a curious child.
Sirius C is Non existen
Congrats new LEVEL OF ANIMATION!!!
Sirius B hit supergiant luminosity (M0Ib) and expanded to 3 AU during its red giant phase. Sirius A became M2.5II during its red giant phase and expanded to 1.5 AU
Became?
Bro Sirius A is not dead yet, we can see it in our night sky
So sirius b is 2x bigger than sirius A?
that's was pretty impressive though even so the Betelgeuse that was over 13solar mass is over 100,000 Solar luminousity it was half of the Sirius B Red giant's maximum luminousity
I really like how this was so entertaining!
buh t this isnt entertainment channel
I've come back to this video at least 10 times, it's really good. Nice work
"I'm so dense right now" I can't XDDD
Let colldle and boom killonova
I subbed! Love you're animations 💖
I love the personality of the stars and planets.
So do I ^^
Yeah Sirius B wasn't always an white dwarf since It was once an B type star in Its life.
That's why the star is called that
@@gamering2354 Lol no. In systems with multiple stars, they name them in alphabetic order, A,B,C.. etc. Thats why they are called Sirius A and Sirius B. Just like Alpha Centaury A and Alpha Centaury B.
@@gamering2354 that serves better as a joke
Ok but B-type stars turn into Neutron Stars
Sirius B was like Bellatrix on its earlier life...a blue star that was bright but not massive enough to become a Red Supergiant
That collision ending got me good 😂😂

SIMBAD The system

Sirius (/ˈsɪriəs/) is the brightest star in the night sky. Its name is derived from the Greek word Σείριος (Seirios, lit. 'glowing' or 'scorching'). The star is designated α Canis Majoris, Latinized to Alpha Canis Majoris, and abbreviated Alpha CMa or α CMa. With a visual apparent magnitude of −1.46, Sirius is almost twice as bright as Canopus, the next brightest star. Sirius is a binary star consisting of a main-sequence star of spectral type A0 or A1, termed Sirius A, and a faint white dwarf companion of spectral type DA2, termed Sirius B. The distance between the two varies between 8.2 and 31.5 astronomical units as they orbit every 50 years.[25]
Sirius appears bright because of its intrinsic luminosity and its proximity to the Solar System. At a distance of 2.64 parsecs (8.6 ly), the Sirius system is one of Earth's nearest neighbours. Sirius is gradually moving closer to the Solar System, so it is expected to slightly increase in brightness over the next 60,000 years. After that time, its distance will begin to increase, and it will become fainter, but it will continue to be the brightest star in the Earth's night sky for approximately the next 210,000 years.[26]
Sirius A is about twice as massive as the Sun (M☉) and has an absolute visual magnitude of +1.42. It is 25 times as luminous as the Sun,[13] but has a significantly lower luminosity than other bright stars such as Canopus or Rigel. The system is between 200 and 300 million years old.[13] It was originally composed of two bright bluish stars. The more massive of these, Sirius B, consumed its resources and became a red giant before shedding its outer layers and collapsing into its current state as a white dwarf around 120 million years ago.[13]
Sirius is known colloquially as the "Dog Star", reflecting its prominence in its constellation, Canis Major (the Greater Dog).[19] The heliacal rising of Sirius marked the flooding of the Nile in Ancient Egypt and the "dog days" of summer for the ancient Greeks, while to the Polynesians, mostly in the Southern Hemisphere, the star marked winter and was an important reference for their navigation around the Pacific Ocean.

The star on the left is Sirius B, the one on the right is Sirius A
Also Im pretty sure Modern day is around 3:22
It's on timed section
I love how they just wait a few million years to talk
3:22 present
5:19 black dwarf collision
Sirius A is the brightest star in the night sky, I wonder how bright would be Sirius B before it became a white dwarf
It would make Sirius even brighter in the night sky. Probably the most brightest and luminous star in our sky to the point it may be visible in the daylight.
@@dillantervet9055 there was a Blue Giant named Adhara Class B2III mass of 12 Suns and Luminosity of 38,000Suns..
4.7Million years ago it approachs the Solar System closest by 34 Light years.. Adhara's Immense Luminosity gained over -3.99..
No such star will ever again regain or Exceeds that Magnitude for another 500Millions years
Sadly today its now far away over 430 Lightyears now were just left with Siruis
@@messier8379 lucky it moved far away as 12 solar masses is enough to go supernova. B2III means it is an red giant that is experiencing an blue loop hence why its blue not red. It will expand to an red supergiant then supernova
If it were at its brightest and at its present location it would have apparent magnitude of something like -10 although this is a very rough estimate
I was just wondering if sirius B is a white dwarf, how they still close together?
so when the stars go boom, the other nearby objects doesn't really affected? I thought they will.... idk wiped or something. at least in this case, I thought they wouldn't be together again (unless sirius B died first then they meet each other. but turns out that's not the case)
I never knew I would be this early 😳

🏭🔥🏭 INDUSTRIAL SOCIETY AND ITS FUTURE 🏭💯🏭
▶️Introduction ▶️
1️⃣. The Industrial Revolution 🏭 and its consequences have been a disaster 💣 for the human race. They have greatly increased ⬆️ the life-expectancy 🙏 of those of us who live in “advanced”. countries🇺🇸🇬🇧🇫🇷🇩🇪, but they have destabilized society🌋, have made life unfulfilling 😭, have subjected human beings to indignities 🙈, have led to widespread psychological suffering❗️🧠❗️(in the Third World 🇸🇳🇵🇸🇸🇴🇿🇼 to physical suffering as well) and have inflicted severe damage on the natural world 🔥🌳🔥. The continued development of technology will worsen the situation 📞➡️📱➡️⌚️➡️❓. It will certainly subject human beings 👨💼👩💻👩🎓🕵️♂️👨🏫👨🎨👰 to greater indignities and inflict greater damage on the natural world 🌲😢🌳, it will probably lead to greater social disruption 😱 and psychological suffering 🧠⛏️, and it may lead to increased physical suffering even in “advanced” countries 🇸🇬🇨🇦 🇪🇸🇸🇪.
2️⃣. The industrial-technological system may survive 🍃 or it may break down 🍂. If it survives, it MAY eventually achieve a low ⬇️ level of physical 💪 and psychological 🧠 suffering, but only after passing through a long 🕐🕑🕒🕒🕓🕔🕕🕖🕗🕘🕙🕚🕛🕜🕝🕞🕟🕠🕡🕢🕣🕤🕥🕦🕧and very painful 🤕 period of adjustment and only at the cost 💰 of permanently reducing human beings and many other living organisms 👨👩🦰🐼🦁🐷🐸🐱 to engineered 👷♂️👷♀️ products and mere cogs ⚙️ in the social machine. Furthermore, if the system survives, the consequences will be inevitable 💯: There is no way of reforming 💭 or modifying ❗️ the system so as to prevent it from depriving people of dignity and autonomy🔓.
3️⃣. If the system breaks 💔 down the consequences will still be very painful 🤕. But the bigger 💪 the system grows ⬆️ the more disastrous the results of its breakdown will be, so if it is to break down it had best break down sooner 🔜 rather than later 🔚.
4️⃣. We therefore advocate a revolution ✊against the industrial system 🏭. This revolution may or may not make use of violence 🔫; it may be sudden 💥 or it may be a relatively gradual process 📈spanning a few decades. We can’t predict 🔮 any of that. But we do outline 🔲 in a very general way the measures 📏 that those who hate the industrial system 🏗 should take in order to prepare the way for a revolution ✊ against that form of society. This is not to be a POLITICAL 🏛revolution. Its object will be to overthrow not governments but the ecoqnomic 💰 and technological 💻 basis of the present society.
5️⃣. In this article we give attention to only some of the negative 👎 developments that have grown out of the industrial-technological 🏗📱 system. Other such developments we mention only briefly ⏱or ignore altogether. This does not mean that we regard these other developments as unimportant 🚫. For practical reasons we have to confine ⛓️ our discussion to areas that have received insufficient public attention or in which we have something 🆕 to say. For example, since there are well-developed environmental ♻️ and wilderness 🌱🌳🍃movements, we have written 📝 very little about environmental degradation 📉or the destruction of wild nature, even though we consider these to be highly important ❗️.

@@messier8379 That's not what I meant.
Sirius A and B are coincidentally named after their star types. My confusion was that Sirius B is (was) a B type star, which would be bigger than Sirius A, an A type star. This is the case because Sirius B, which was the bigger companion, is currently a white dwarf. It's now smaller than Sirius A, the A type, larger companion star. If it wasn't, Sirius A would've been Sirius B, and Sirius B would be Sirius A.
I'm aware of that stars and some celestial objects are named after females.
Asteroids are named after women. Pallas, Vesta. You name it ;)
I'm literally named after the Roman Goddess of agriculture, grains, and corn.

4:05 Sirius A gets really big, the binary orbits are f'ed up rlly bad
4:07 Sirius A Goes through helium flash, then slowly grows as it burns helium for like an eternity
4:40 Sirius A goes into AGB
4:45 Sirius A shoots a bunch of hydrogen out in space, Sirius B eats it like a champ
4:59 Sirius A Grows untill it implodes into white dwarf of 0.0100 mass of the sun
5:03 they both hang out and cool for like billions and billions of years, sun just enters AGB
5:18 they get bored so they collide [realistic] sun become white dwarf of 0.0800 mass of sun, end of video
Dude you flipped Sirius A and B
The small one is A
@@57z2 The current Sirius B is a dead star, but it was once much bigger and brighter than the currently alive Sirius A star
i know, why does that matter?
1:46 *deltarune*
When Sirius B form, it was a red dwarf, but it goes supernova and turn into a white dwarf
Well kids to get ready to watch it from heaven
Love ur vids
Can you do Cappella and Algol binary history next time?
"You gonna shoot... Fireworks?"
0:18 Sirius A 20 suns luminosity Sirius B 586 suns luminosity
@TheRandomChannelCreatedByAnAsian Larger stars are usually brighter, and live shorter.
Did Sirius b supernova
585 solar luminosity
The fact how the 2 stars collided in like not even a second had me laughing lol
So will there be a G-type star one, or is the solar system enough?

coming soon: Milky Way timeline
I hope you read it dogepro and good luck n.n
Ez 1. Gas collapse
2. Stars born into a clustee 3. Dwarf galaxy 4. A black hole gets mass in center into super massive blackhole 5. Collisions 6. Now 7. LMC collision 8. Andromeda galactic union 8. Eleptical galaxy 9. Active saggi/andro AB* blackhole 10. Die
@@Philippine_Navyist16 worse than doge pro
my mans finally back. also the animation went from 10 to 1000 ngl
your videos make astronomy so cute
I love how it just said big shot at the end
🙂
Wait Sirius B/A was a white dwarf the whole time? I thought they were a neutron star smh
I still want to murder more stars
Yes I Knew That
The Music is kind 8 Bit Sounded
Music in 5:00 :
I think it was awarded the first one of the most important
As a "digital" or "local" astronomer I'm kinda impressed
your new pfp looks 🔥🔥🔥
They’re like the 2 muppets that react to stuff
Statler and Waldorf! I didn't think of that, but that totally works! XD
4:48 text: It’s too far to become a supernova (bottom left corner)
I like how the stars talk to each other
