The spin period of EX Hydrae.

KING A.R. and WYNN G.A.

Abstract (from CDS):

We show that the spin period of the white dwarf in the magnetic cataclysmic variable (CV) EX Hydrae represents an equilibrium state in which the corotation radius is comparable with the distance from the white dwarf to the inner Lagrange point. We also show that a continuum of spin equilibria exists at which Pspin is significantly longer than ∼0.1Porb. Most systems occupying these equilibrium states should have orbital periods below the CV period gap, as observed.
