Abstract: This article is a brief survey of mathematical work, joint with Yilun Wu and Juhi Jang, on models of stars and galaxies. It is a sequel to the survey article by Yilun Wu [Quart. Appl. Math. 78 (2020), pp. 147–159]. The models consider rotating stars (or galaxies or gaseous planets) as composed of particles subject to gravity. Under appropriate conditions, global families of isentropic steadily rotating stars are shown to exist. Local families are also shown to exist even in the presence of variable entropy and arbitrary axisymmetric angular velocity.
