In a Type 1A nova, is the giant, companion star annihilated in the explosion or punted away across the galaxy like an enormous cosmic cannonball? Do we know? Have either of these things ever been observed to happen? Also, minor correction: at about 2:20 you say that as the core's fusion slows down and stops, the outward radiation pressure drops, and so _gravity increases._ The star's mass isn't changing at this point, so obviously its gravity stays exactly the same. The *_effect_* of the star's gravity _does_ increase, as the radiation pressure that _was_ countering it isn't there any more. Excellent channel - just subscribed and am enjoying working my way through your past vids. --S
The progenitors of type 1a are polar (highly magnetic) white dwarfs. The mass stolen from a companion star is sucked in at the polar regions. It accumulates INSIDE the stellar corpse. Like a giant pressure cooker, they all have the same breaking point, the same interior capacity (230 million Gauss). The chandrasekhar limit is the net minimum mass of a pulsar. It has nothing to do with the explosion.
The progenitors of type 1A are polar white dwarfs (like AN Ursae Majoris B.) The chandrasekhar limit has nothing to do with why the explode. 1.44 S.U. is merely the minimum net weight required to form a pulsar. 🤠✌️

Why don't heavy stars fuse iron even at the net energy loss? Why heavy stars don't overshoot the iron peak? Iron cores have enough gravitational energy to spend on iron fusion but they don't.
universe goes hard

Quick answer, yes. Either Awesome or Epic. Watch the video for a more detailed explanation.
Lol, thanks Edward! :-)
Dude your channel has such great stuff ......Keep it up man.....
Even though I already knew all of this information your video is excellent.
Thank you! :-)
you give me extra knowledge i love it

What about killonovas
good channel & great videos, you will be big one day :-)
Thanks Matt, really appreciate the support! :-)
Great channel
Thank you.
when the star starts to producing iron in its core , it has only seconds before it undergoes a supernovae
no iron stays for a oittle bit
What's the difference between 1b, 1c and type 2? Wiki hasn't been very helpful in clearing this up
nice
Supernovaeaeaeaeaeaeaeae
Supernovee haha
The plural is Supernovae
