What is Yellow dwarf star cycle?

Answer 1

A yellow dwarf star, like our Sun, undergoes a life cycle that begins with its formation from a nebula of gas and dust. It spends the majority of its life in the main sequence phase, where it fuses hydrogen into helium in its core, producing energy and maintaining stability. After exhausting its hydrogen fuel, the star expands into a red giant, eventually shedding its outer layers and leaving behind a hot core. This core, known as a white dwarf, will gradually cool and fade over billions of years.
