Simple Model of a Rotating Star as a Huygens-Roche Figure

  • Published:
Astrophysics Aims and scope

Simple analytic formulas are obtained for the equatorial radius and relative rotation velocity of a star as functions of its absolute and relative angular momentum as a Huygens-Roche figure. The results are compared with numerical simulations of the structure of rotating stars and it is shown that the analytic model considered here is sufficient for describing the corresponding parameters.
