O. ; Ipser, J. R. Abstract In a post-Newtonian approximation, it is shown that the emission of gravitational radiation makes a Dedekind-like mode of second-harmonic oscillation secularly unstable in all of the rotating members of a certain Maclaurin-like sequence of axisymmetric stellar systems. The limiting, nonrotating member of the sequence is a point of neutral stability, and it is also the point of bifurcation at which a Dedekind-like sequence of nonaxisymmetric stellar systems branches off from the Maclaurin-like sequence. The Maclaurin-like and Dedekind-like systems that are considered here belong to the family of stellar systems, of the form of elliptical disks, that has been constructed by Freeman and by Hunter.
