UNDERSTANDING AND UNIFYING THE GAMMA RAYS EMITTING SCENARIOS IN HIGH MASS AND LOW MASS X-RAY BINARIES
ISSI-BJ TEAM
PI: DR. JIAN LI (DESY)
INTRODUCTION
The physical mechanisms responsible for particle acceleration and the nature of the resulting high energy emission are two of the key questions of current astrophysics research. X-ray binary systems visible in gamma-rays are especially interesting laboratories for this investigation. This gamma ray emission has been explained by wind interactions, microquasar jets and the propeller effect. All of these are realized both in high mass X-ray binaries (HMXBs) and low mass X-ray binaries (LMXBs). However, even with the same underlying scenario, the gamma ray emission observed from HMXBs and LMXBs are found to be different. With this project we plan to enlarge the sample of sources and to systematically investigate similarities and differences between different systems, finally seeking to unify the gamma-ray launching conditions for HMXBs and LMXBs. The project will also be timely to prepare observing opportunities for Chinese astrophysics satellites, e.g., HXMT-Insight, Einstein Probe and eXTP as well as ground based gamma-ray observatories.
