Intriguing X-ray and optical variations of the gamma Cas analog HD45314
G. Rauw, Y. Nazé, M. A. Smith +11
A growing number of Be and Oe stars, named the gamma Cas stars, are known for their unusually hard and intense X-ray emission. This emission could either trace accretion by a compa…
IGR J19552+0044: A new asynchronous short period polar: "Filling the gap between intermediate and ordinary polars"
G. Tovmassian, D. Gonzalez-Buitrago, J. Thorstensen +23
Based on XMM--Newton X-ray observations IGR J19552+0044 appears to be either a pre-polar or an asynchronous polar. We conducted follow-up optical observations to identify the sourc…
Long orbital period pre-polars containing an early K-type donor stars. Bottleneck accretion mechanism in action
G. Tovmassian, D. Gonzalez-Buitrago, S. Zharikov +6
We studied two objects identified as a Cataclysmic Variables (CVs) with periods exceeding the natural boundary for Roche lobe filling ZAMS secondary stars. We present observational…
