An estimation of structure parameters of rotationally and tidally distorted polytropic models of stars in the presence of Coriolis force

In this paper we propose suitable modifications in the concept of Roche equipotential to account for the effects of Coriolis force on its equipotential surface besides the usual effects of gravitational and centrifugal forces and use this in conjunction with Kippenhahn and Thomas, 1970 approach in a manner earlier used by Mohan et al, 1990 to incorporate the effects of Coriolis force in the equations of stellar structures. The proposed method has been used to compute the equilibrium structures, shapes and other observable parameters of rotationally and tidally distorted polytropic models of stars. The results thus obtained have been compared with the corresponding results earlier available in literature in which the effects of Coriolis force had not been taken into account.
