Optical variability of the supersoft source RX J0019.8+2156.
GREINER J. and WENZEL W.
Abstract (from CDS):
We present a 100yr optical lightcurve of the recently discovered supersoft X-ray source RX J0019.8+2156 as deduced from photographic plates of Harvard and Sonneberg Observatory. Apart from the periodic orbital variations two different timescales of optical variability are discovered. The timescales and amplitudes of this variability are discussed in the framework of the steady nuclear burning model.
