Spectroscopic Evidence for Appearance of a New Decretion Disk Around IGR J06074+2205
Abstract
We report on a new episode of decretion disk formation in the IGR J06074+2205 system. Our spectroscopic data permit us to measure peak separation in the double-peaked H-alpha line as 408+/-55 km/s and hence to determine the disk radius as 1.6 star's radii. These findings permit us to predict possible new X-ray activity of IGR J06074+2205 in the nearest future.
