  • Sirius is the brightest star in the sky and visible from most of the planet. We've been staring at it for 1000s of years, but the more we learn about it, the weirder it gets.

    *Note about the equation at **07:14** -* While what I'm saying is correct, I've been informed the symbol 'σ' is a constant in this specific context, not area like it is in other contexts. A better way to have written the equation would have been L ∝ A T⁴, with 'L' for luminosity and 'A' for area. Unfortunately, TH-cam doesn't allow me to replace videos on a whim. We'll have to live with this pinned correction (and the pop-out correction card I added to the video itself).
    That being said, Nebula let's me fix and replace videos whenver I want. Yay Nebula! The equation has been fixed there.

      Is it possible that Sirius B's Rosch limit was smaller than it's radius when Sirius A was inside it, due to it's low density? And if so, if Siruis A was still outside of that Rosch limit, wouldn't this solve the weirdness?

    • @NathanielStickley

      Yikes! Error in the Stefan-Boltzmann Law section. It looks like you're implying σ is the surface area; it's the Stefan-Boltzmann constant. Instead of the expression for intensity, I. You actually want to use the luminosity instead: L = AI = AσT⁴, where A is the surface area (4 πr², since it's spherical).

    • @ScienceAsylum
      @ScienceAsylum  13 วันที่ผ่านมา +2

      @@NathanielStickley Thanks for the correction. I think all these years my brain has been doing a few things that have cancelled each other out: (1) Assuming σ is area like it is in _every_ other context, (2) being ambiguous about what "intensity" is, and (3) ignoring constants like any good theorist does. So L = σAT⁴ became L = σT⁴.
      I'll see what I can do about fixing this error.

      @@ScienceAsylum Ah, ok. It might help to remember that σ is oftentimes the *cross-sectional* area, but the relevant area when computing luminosity is the *total* surface area.

      I was bored and calculated that for Sirius to yeet out an asteroid 126 million years ago, and for it to reach earth 66 million years ago from 8,611 lightyears away, it would have been traveling at about 43km/s for those 60M years.
      Asteroids usually travel 17-25 km/s, so unlikely, but if Sirius was feeling passionate it might have thrown the asteroid twice as fast to be sure it got the job done...
      Another Googling further, it seems the asteroid did travel only 20km/s, and from the northeast (sirius is closer to the equator usually) (or middle declination to use newly learned terms)
      I honestly would not have thought those 60M years are still like twice too short of a time to make up for 8,6 lightyears... light is fast yall

    Kerbal Space Program taught me that a body in a highly elliptical orbit which dips into atmosphere can gradually circularize, losing almost entirely apoapsis while its periapsis remains about the same. It seems reasonable to me to assume Sirius A and B's current orbit as a final position, and simulate in reverse to find out what their orbits would have been back when Sirius B first grew into a giant. My guess is that they had an elliptical orbit which didn't cause them to collide with each other or come close enough to experience tidal disruption for much of the stars' lives, but when Sirius B grew into a giant star, it at some point became big enough for the close point in their orbit to cause more significant interactions between the two stars.

  • @ThanosElohim
    @ThanosElohim 12 วันที่ผ่านมา +4

    It’s possible that the orbital configuration changed at some point after Sirius B became a white dwarf. This could happen if there was a third star that got thrown out of the system. The loss of dynamical energy would then tighten the orbit of the remaining stars.

    • @tomfeng5645
      @tomfeng5645 13 วันที่ผ่านมา +7

      Without some complex interaction, two stars cannot just become a binary on their own, as any singular interstellar object entering a star system necessarily is on a hyperbolic trajectory (has enough energy to leave the system). Any disruption must have required the existence of a third object of similar mass that was subsequently sling-shotted out. Another star passing though, capturing 1/2 members of a binary system, a trinary system that eventually destabilized, all seem like reasonable candidates, but there's no candidates for such a third objects, and the wide range of possibilities and timeframes make it difficult to narrow down what to look for.

    Calling Alvan Graham Clark an amateur astronomer does a great disservice to the man. He and his father Alvan Clark were the foremost telescope maker of their time. Alvan Clark and sons refractors are still renowned today as the pinnacle of the art of achromatic refractors. They built the largest refractors ever constructed, including the 40 inch diameter refractor at Yerkes observatory, and the 36 inch at Lick observatory. Clark's refractors were the finest observatory instruments available at the time, and although later eclipsed in power by reflector telescopes, continue to do science today. Clark discovered Sirius B while testing a telescope of their own construction, An 18.5 inch lens which was the largest in the world at that time.

    It's entirely possible that Sirius A and Sirius B did not capture each other's orbits until after Sirius B shed its original mass.

      Yes, but I doublt that even today, the gears of a telescope are that precise.

    • @David_Last_Name

      It's what he needed the long history of records for. He wasn't directly observing it wobble. They had precise enough measurements that they could say "it should be at 6hr32m right ascension, why is it only sitting at 6hr30m?" or something to that effect. Then going back over 50 years he could see it would slowly drift from being slightly to the right of where it should be to slightly to the left, with a 50 year wobble.

    If Sirius B started out with five times the mass of the Sun, it had to lose 80% of its mass over its lifetime, mostly when it was a red giant. This amounts to four solar masses. How much of this mass was picked up by Sirius A, and what was its initial mass? And what are the implications for the orbital dynamics over the lifetime of the system. Sirius A does have weirdly high metallicity, presumably due to scooping up material lost by Sirius B. There are lots of interesting topics about this star system.
