摘要:
Insight-HXMT as the first Chinese X-ray astronomical satellite has successfully worked for more than four years and produced many new discoveries in compact objects and related high energy astrophysical processes. Here I will briefly introduce the main science results about X-ray binaries including black hole (BH) and neutron star (NS) systems, specially concentrating on the work finished in Wuhan University. At first we report the non-thermal emission evolution connecting corona-jet relation in a BH X-ray binary, the new results on low-frequency quasi-periodic oscillations of BH systems and possible physical origin are also introduced. The cyclotron resonant scattering features (CRSFs) are the unique tool to measure the magntic field of neutron stars, the relations of CRSF energy with X-ray luminosity discovered by Insight-HXMT provide the new clues of understanding accretion physics and geometry on the surface of NS.
