KIDS TRIVIA

Detailed explanation-1: -Stellar masses are not fixed, although they change for single stars only on long periods. Low-mass stars, like the Sun, lose material through modest winds, about 10−14 M⊙ yr−1 while in the hydrogen core burning (main sequence) phase. Turbulence and magnetic field dissipation appear responsible for such mass outflows.

Detailed explanation-2: -Giant stars use up their hydrogen fuel quickly, resulting in short lifetimes. An eight solar mass star will live less than 100 million years. At 10-15 solar masses, the lifetime of the star drops to only 10-20 million years. The most massive giant stars are believed to live no more than a few million years.

Detailed explanation-3: -The length of a star’s life depends on how fast it uses up its nuclear fuel. Our sun, in many ways an average sort of star, has been around for nearly five billion years and has enough fuel to keep going for another five billion years. Almost all stars shine as a result of the nuclear fusion of hydrogen into helium.
