Variable X-Ray Sources in the Rho Ophiuchi Dark Cloud
Abstract
Two different observations with the Einstein Observatory of the central region of the Rho Oph dark cloud, made six months apart, reveal the presence of numerous sources. There is strong evidence that the sources are variable. The variations in apparent luminosity over a six-month period range from a factor approximately 2 to a factor approximately 10.
