Hi there.
00:01
So for this problem, we are told to describe the evolution of a massive star that is, say, 20 times the mass of the sun, up to the point at which it becomes a supernova.
00:24
And how does the evolution of a massive star differ from that of the sun? and why? so a massive star will leave the main sequence once its core of hydrogen is depleted.
00:51
So after that time, it becomes a super giant star.
01:03
And it will begin fusion a variety of heavier elements.
01:10
Fusion of heavier elements.
01:15
For example, carbon, carbon fusion, later neon fusion, oxygen, oxygen, and silicon.
01:39
Now, after the inner quorum becomes iron, then until iron, because that which requires energy to fuse.
02:00
So that is the star of the star's death.
02:07
And we'll experience a core collapse, core collapse, and create a neutron star from its core.
02:22
Create a neutron star from its core.
02:34
And the rest of the star explodes into a supernova.
02:39
The rest explodes into a supernova.
02:53
So that is the evolution of a star like this...
