Support for a white dwarf in the Be star binary γ Cassiopeiae.

APPARAO K.M.V.

Abstract (from CDS):

The recently discovered orbital period for γ Cas and the modulation period in X-rays and optical are consistent with the orbital period-spin period relation for white dwarfs derived from a similar relation found for Be star - neutron star binaries. This lends support for the existence of a white dwarf in the γ Cas binary.
