Optical variability of the LMC supersoft source RX J0513.9-6951
Abstract
We present optical spectroscopy and photometry of the LMC supersoft source (SSS) RX J0513.9-6951. Through the exceptional monitoring capabilities of the MACHO project, we show the optical history of this object for a≈3 year period. Recurring low states, in which the optical brightness drops by up to a magnitude, are observed at quasi-regular intervals. Analysis of the high state data reveals a small modulation with a semi-amplitude of ≈0.02 …
