摘要：
The recently discovered orbital period for gamma 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 gamma Cas binary.
