Finding Planetary and other Hierarchical Systems in Archived X-Ray Data
Abstract
Planetary systems and hierarchical multiples are common among astronomical systems composed of main-sequence stars. Many members of such hierarchies are expected to survive stellar evolution, and may therefore be part of active X-ray binaries (XRBs). Bright XRBs therefore provide excellent opportunities to observe the associated phenomena, including eclipses due to planetary passages across small X-ray-emitting regions, and spikes due to binary self lensing. We have embarked on searches of archived X-ray data and will report on an intriguing planetary candidate located in an X-ray binary that inhabits an external galaxy.
