Identifying Large Scale Features on the Surface of Contact Binaries with Sub-Arcsecond Techniques
Published online by Cambridge University Press: 13 May 2016
Abstract
We summarize multifold evidence for the presence of a hot spot region in contact binary VW Cephei. We interpret this feature as a photospheric burn and the preferential site of flares in EUV and X rays. With its trigonometric parallax of 0.041 arcsec VW Cep is a promising target for a milliarcsecond resolution investigation of the nature of surface features both in optical region and in IR.
