Study on Gamma-ray binaries with the LHAASO data

The study of gamma-ray binaries using LHAASO data provides crucial insights into high-energy astrophysics. These binaries, consisting of a massive star and a compact object, emit radiation primarily in the MeV to TeV range. LHAASO’s sensitivity enables detailed observations of key sources, including HESS J0632+057, PSR J2032+4127, GRS 1915+105, SS 433 (w1 & e1), and LS I +61 303, each exhibiting unique emission characteristics, periodic variability, and orbital modulations. SS 433, a microquasar, provides a valuable case for studying relativistic jets, while HESS J0632+057’s wind-wind interactions highlight its eccentric orbit. PSR J2032+4127 and GRS 1915+105 contribute to understanding pulsar-driven and accretion-powered emissions, while LS I +61 303 reveal complex particle acceleration mechanisms. LHAASO’s WCDA and KM2A detectors provide high-significance detections of these sources, enabling precise spectral and temporal monitoring to enhance models of high-energy emissions in extreme astrophysical environments.
