assuming though that i have two spheres made of the same material, would the differing densities make a difference?
also, i think that pixel you misunderstood. i realize that as it spins it should get more dense as the volume is shrinking, but that is not my question.
I dont think gravity has much to do with it. its a GRAVITY bound sphere. it would form an ellipsoid. the denser the object the stronger the gravity so yes for any given rotation rate the degree of flattening will be less.
i presume this is about the neutron star you mentioned in your other post.
