Characteristics of Main Sequence Stars

Characteristics of main Sequence Stars main - Sequence Stars obey several relations (which are mostly pre- dictable from homology). main Sequence Stars obey a mass-luminosity relation, with L . M . The slope changes slightly over the range of masses; be- tween 1 and 10M , The relation flattens out at higher masses, due to the contribution of radiation pressure in the cen- tral core. (This helps support the star, and decreases the central temperature slightly.) The relation also flattens significantly at the very faint end of the luminosity function. This is due to the increasing important of convection for stellar structure.

Changes in metallicity shift the location of the ZAMS; the metal-poor main sequence is blueward of the solar metallicity main se-quence. This is primarily due to the reduced amount of bound-free absorption throughout the star (which only comes from metals). The smaller opacity allows the energy to escape more easily, and
