If a star is 20 times heavier than the sun, what will it be in future?

Options

A. A white dwarf
B. Supernova
C. Red giant star
D. None of these

Explanation

To determine the future of a star that is 20 times heavier than the Sun, we can follow these steps:

### Step 1: Understand Stellar Mass
- The mass of a star plays a crucial role in its life cycle. Stars with greater mass have different evolutionary paths compared to less massive stars.

### Step 2: Identify the Mass Thresholds
- Stars that are significantly more massive than the Sun (typically more than 8 times the mass of the Sun) will undergo different processes at the end of their life cycles.

### Step 3: Core Collapse
- As a massive star exhausts its nuclear fuel, its core will collapse under the force of gravity. For a star that is 20 times the mass of the Sun, this process is more pronounced.

### Step 4: Formation of a Supernova
- The collapse of the core leads to a supernova explosion. This is a violent event that occurs when the outer layers of the star are expelled into space.

### Step 5: Resulting Objects
- After the supernova, the remnant core can become either a neutron star or, if the mass is sufficient, collapse further to form a black hole.

### Conclusion
- Therefore, a star that is 20 times heavier than the Sun will likely end its life as a supernova and can potentially become a neutron star or a black hole.
