Question

What is expected to happen to the Sun after the hydrogen in its core is exhausted?

विकल्प

• The outer envelope of the Sun is expected to expand, and the Sun will evolve into a red giant

• The Sun will immediately collapse into a white dwarf without any expansion

• The outer envelope will contract, and the Sun will become a blue giant

• The Sun will explode as a supernova shortly after hydrogen exhaustion

Answer 1

After the hydrogen in the Sun's core is exhausted, the outer envelope of the Sun is expected to expand, and the Sun will evolve into a red giant. This expansion follows the accumulation of helium and core contraction in the stellar evolution sequence.
