A simple tool for calculating centrifugal deformation starting from 1D models of stars or planets
Abstract
We describe a tool which is able to calculate the centrifugal deformation of a rotating star or planet starting from a 1D non-rotating model, for conservative (i.e. cylindrical) rotation profiles. This tool applies an iterative approach based on the Self-Consistent Field (SCF) method while preserving the pressure profile as a function of density. The resultant model is suitable for stellar pulsation calculations, thus making this tool suitable for parametric asteroseismic investigations. It can also be used to calculate the deformation of rapidly rotating planets such as Jupiter and Saturn which contain internal discontinuities.
