Viscous effects in rapidly rotating stars with application to whitedwarf models. III. Further numerical results.
Abstract
Improved viscous evolutionary sequences of differentially rotating, axisymmetric, nonmagnetic, zerotemperature whitedwarf models are constructed using the relativistically corrected degenerate electron viscosity. The results support the earlier conclusion that angular momentum transport due to viscosity does not lead to overall uniform rotation in many interesting cases. Qualitatively different behaviors are obtained, depending on how the total mass M and angular momentum J compare with the M and J values for which uniformly rotating models exist. Evolutions roughly determine the region in M and J for which models with a particular initial angular momentum distribution can reach carbonignition densities in 10 b.y. Such models may represent Type I supernova precursors.
