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.
