Shrinking of the Be disk whilst the X-ray activity increases in the binary system A0535+262
Abstract
We report on the evolution of the H & alpha; equivalent width (EW) of the Be/X-ray binary system A 0535+262/HD 245770, using observations performed with the spectrograph COLORES at the 0.6 m telescope BOOTES-2 (M & aacute;laga, Spain) on 2015-01-27 at 22:05:31.736 UTC (MJD 57049.920), and with the spectrograph located at the 51 cm telescope of the Observatorio de Aras de los Olmos of the University of Valencia on 2015-01-29 at 01:00:00 UTC (MJD 57051.042).
