Investigating Long-Term Behaviour of X-ray Binaries Using Archival Data

Investigating Long-Term Behaviour of X-ray Binaries Using Archival Data

Long term modulations have been detected in a wide variety of both low and high-mass X-ray binaries. The All Sky Monitor on board the Rossi X-ray Timing Explorer provides the most extensive (~15 years) and sensitive X-ray archive for studying such behaviour. Since those variations were often intermi...
