Question

How is the death of a very large star different from the death of a small star?

Answer 1

Hint: All stars die differently despite the fact that they belong to the same set of collections. This is because, how a star will reach its end depends on the fact that how big it is, that is, how much mass it has. This is why the death of a very large star differs considerably from the death of a small star.

Complete answer:
When a very large high-mass star has no Hydrogen or Helium gas fuel left to burn, it expands and becomes a Red Supergiant. These Supergiants destroy themselves by a very huge explosion, which is called a Supernova. The death of these massive stars can trigger the birth of Neutron stars or even Black holes. This fact depends on the mass of the Progenitor star.
Now, in case of smaller stars like that of our sun. When the star has no Hydrogen fuel left for fusion at its core. The core of the star collapses due to gravity, which results in Helium being burnt at the core to produce Carbon. This expands the star to a Red Giant .Once this Helium in the core is totally consumed, the Carbon core will eventually cool and become a White Dwarf.

Note:
The age of a star can be in ranges of billions of years but they cannot live on forever. At first, all stars first run out of their Hydrogen gas fuel. In the process of fusion at the core of these stars, this Hydrogen is being converted into Helium which also acts as a fuel for the core. But once, these Helium gas fuel is totally consumed by the star, it eventually dies. This process is inevitable.
