Synoptic observations of the supersoft binary MR Velorum (RX J0925.7-4758): determination of the orbital period.

SCHMIDTKE P.C. and COWLEY A.P.

Abstract (from CDS):

Synopic observations of MR Velorum (RX J0925.7-4758) taken over 5 months with the YALO telescope at CTIO have allowed us to narrow the window of acceptable orbital periods. When these data are then combined with photometry taken over the past decade, a well-determined period of 4.0287822±0.0000026 days is found. It is now possible to phase together various published photometric and spectroscopic data.
