Review of low‐mass X‐ray binaries near the Galactic center

Abstract

Results of observations of several LMXBs in the Galactic center region carried out with the ART-P telescope on board GRANAT observatory are briefly reviewed. More than dozen sources were revealed in this region during five series of observations which were performed with the ART-P telescope in 1990-1992. The investigation of the spectral evolution of persistent emission of two X-ray bursters GX3+1 and KS1731-260, discussion of QPO and spectral variations detected from the very bright Z-source GX5-1 and studying the pulse profile changes of the pulsar GX1+4 were carried out.
