Abstract
In this Research Note we present new gravity-darkening exponents () for several stellar evolution models from the ZAMS up to the giant phase. The models were computed using the MESA code (version 7385) for the composition and , adopting A09 opacities and a mixing length parameter of . Results were calculated using the triangle strategy, for initial stellar masses of 1.0, 1.5, 2.0, 2.5, 3.0, 5.0, 7.0, 10.0, 15.0, and 20.0 , and provide an update on previously available values that used older models.
