X-Ray to Infrared Observations of the Cataclysmic Variable KO Velorum (E1013-477)
Abstract
Simultaneous photometric and spectrometric observations of the source E1013 - 477 in X-ray, UV, optical, and IR bands are presented. Evidence is found in support of the recently proposed orbital period of 10.12 hr. The X-ray spectra (0.1-10 keV) are well fitted by a single power law of photon index -0.8 with interstellar absorption NH not greater than 10 exp 21/sq cm. Discussing the classification of the source in the frame of the magnetic cataclysmic variables, it is concluded that E1013 - 477 is probably a new intermediate polar candidate.
