How hot is a blue dwarf
Web17 jan. 2024 · In the case of a main-sequence star with a mass less than 0.5 M☉, the helium does not fuse to its core because it doesn’t get hot enough. Such a white dwarf would take more time than the age of the universe (13.7 billion years) to burn off all its hydrogen and become a blue dwarf. Stars With Low To Medium Mass Web13 mrt. 2024 · A blue giant star is a swelling middle-aged star that is running out of hydrogen to burn but hasn’t started burning helium. It is blue because it burns hotter as it begins using the remaining hydrogen. After a few million years, these type of starts will begin to burn helium and swell up further. 00:03 12:50 Brought to you by Sciencing Red Giant
