Descripción
Gamma-ray binaries are rare stellar systems where a compact object interacts with a massive companion star, producing high-energy emission in the MeV–TeV range. Leveraging the sensitivity of LHAASO’s WCDA and KM2A detectors, we analyze multiple key systems, including HESS J0632+057, PSR J2032+4127, GRS 1915+105, SS 433, LS 5039, and LS I +61 303. These sources display diverse behaviors such as orbital-phase-dependent variability, relativistic jets, and wind-driven interactions.
In total, six binary candidates have been identified in the LHAASO northern sky map. The morphology and energy spectra of all these sources have been systematically modeled. Notably, flaring activity has been observed during the orbital phases of LS I +61° 303 and HESS J0632+057, highlighting dynamic particle acceleration processes in these systems.
Our study demonstrates LHAASO’s capability to resolve both spectral and temporal features with high significance, offering deeper insight into the mechanisms driving gamma-ray emission in compact binary environments.
