What process happens in red dwarf stars that help them live so long?
Hydrogen is trapped in the core and has to conserved.
The entire star is convective which brings hydrogen to the core.
The entire star is radiative which brings hydrogen to the core.
The cores are small and made entirely of helium which fuses more efficiently than hydrogen.
Solution
Answer- Option (b)
Explanation-
The fundamental difference between red dwarf and main sequence star is that red dwarf contains core, convective zone but not radiative zone while main sequence star like our Sun also contai radiative zone. The convective zone connects directly to the core of the red dwarf, the helium byproduct created by fusion is spread throughout the star. This convection brings fresh hydrogen into the core of the star where it can continue the fusion process.
I will be glad to see your comment if you have any query. Thanks...
