Optical variability of the Large Magellanic Cloud supersoft source RX J0513.9 - 6951 from MACHO Project photometry

Monthly Notices of the Royal Astronomical Society, Volume 280, No. 4, Year 1996

Using the exceptional monitoring capabilities of the MACHO project, we present here the optical history of the LMC supersoft source (SSS) RX J0513.9 - 6951, for a continuous 3-year period. Recurring low states, in which the optical brightness drops by up to a magnitude, are observed at quasi-regular intervals. This provides a crucial insight into the nature of the supersoft sources and, in particular, a chance to investigate the poorly understood behaviour of their accretion discs. Analysis of the high-state data reveals a small modulation of semi-amplitude ∼ 0.02 mag at P=0.762 78 ±0.000 05 d, a period which is consistent with the current 'best' suggested spectroscopic value.
