A low-mass red dwarf (0.08 M

Question

A low-mass red dwarf (0.08 M < M < 0.4 M) experiences which of these fusion reactions as the last fusion reaction in its core?

Quizplus · Accepted Answer

Low-mass red dwarfs, with masses between 0.08 and 0.4 times that of the Sun, do not have sufficient mass and, consequently, core temperatures and pressures to fuse elements heavier than hydrogen. Therefore, the last fusion reaction in their cores is hydrogen fusion, after which they become dim white or black dwarfs without going through the helium or heavier element fusion stages.
