Searching for $\gamma$-ray Counterparts to Very Faint X-Ray Transient Neutron Star binaries

Gege Wang, Zhongxiang Wang

Very faint X-ray transients (VFXTs) are a group of X-ray binaries with low luminosities, the peak X-ray luminosities during their outbursts being only 10${}^{34}$--10${}^{36}$ erg\,s$^…
