» Long-term activity of binary X-ray sources: the importance of monitoring
Presentation duration: 30 minutes
Presenter: Vojtech Simon
We discuss the long-term activity of binary X-ray sources, namely low-mass X-ray binaries and cataclysmic variables. We show that dense series of observations covering the intervals of several years are necessary to resolve the state transitions, like rising and decaying branches of outbursts and high/low states. This is important for our understanding of the physical processes involved. We emphasize the very important role of X-ray monitors like ASM onboard RXTE on our undertanding of the processes operating in X-ray sources. We argue in favor of the development of more sensitive X-ray monitors that will be able to detect the long-term activity of cataclysmic variables, since the current ASM/RXTE is able to observe only about three such systems.
