Magnificent island universe NGC 5033 lies some 40 million light-years away in the well-trained northern constellation Canes Venatici. This telescopic portrait reveals striking details of dust lanes winding near the galaxy's bright core

Spectroscopic Evidence for Appearance of a New Decretion Disk Around IGR J06074+2205

Чт, Август 16, 2012 - 16:17

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..
