A transient supersoft X-ray source in the Large Magellanic Cloud.
ORIO M., DELLA VALLE M., MASSONE G. and OEGELMAN H.
Abstract (from CDS):
We present new X-ray data with an improved position for the supersoft X-ray source RX J0537.7-7034 and propose a candidate for the optical identification. The X-ray source had an "on" and an "off" state and was variable on a time scale of months. The proposed optical counterpart is displaced by only 9 arcsec; it is a blue variable star whith an amplitude modulation in the optical light curve. The optical spectrum shows a blue continuum and the He II λ 4686 emission line.
