How do main sequence stars generate energy
WebMain sequence stars obey a mass-radius relation. However, the relation displays a signi cant break around 1M⊙; R / M˘, with ˘ ˇ 0:57 for M > 1M⊙, and ˘ ˇ 0:8 for M < 1M⊙. This division marks the onset of a convective envelope. Convection tends to increase the ow of energy out of the star, which causes the star to contract slightly ... WebMain Sequence Membership.
