The existence of forms of bifurcation of the axially symmetric series of equilibrium forms was also investigated. The white-dwarf series proved to lack such points of bifurcation, but they were found on the polytropic series for n < 0.808.</font> </td></tr></table> ===Differential Rotation=== * [https://ui.adsabs.harvard.edu/abs/1966PhRvL..17..816O/abstract J.
