Scientific paper

The mechanism proposed by Hameury et al. (1988) for the 114-min periodicity in 6 of the 13 known AM Her magnetic cataclysmic variables (MCVs) is examined in the light of published observational data on EXO 033319-2554.2, a newly discovered 126-min-period MCV (Giommi et al., 1987; Beuermann and Thomas, 1987). The techniques used to estimate the masses of the white-dwarf primaries in MCVs are discussed, and it is concluded that the mass of EXO 033319-2554.2 is significantly greater (by 0.25-0.60 solar mass) than that in the MCVs with 114-min periodicity.
