I will present some results on the existence and
nonlinear stability for the rotating star solutions which are
axi-symmetric steady-state solutions of the compressible
isentropic Euler-Poisson equations in 3 spatial dimensions.
We then apply these results to rotating white dwarf stars to
show its dynamical stability when the total
mass is less than a critical mass, which is related to the
Chandrasekharlimit in astrophysics. This is a joint work
with Joel Smoller.
