In main sequence stars, what happens during nuclear fusion?
a.Large amounts of energy are depleted. b.Large amounts of mass are formed. c.Helium atoms combine to form hydrogen atoms. d.Hydrogen atoms combine to form helium atoms.
Main sequence stars fuse hydrogen atoms to form helium atoms in their cores. ... Smaller bodies — with less than 0.08 the sun's mass — cannot reach the stage of nuclear fusion at their core. Instead, they become brown dwarfs, stars that never ignite.
