X-Ray Bursters A1742-294 and SLX1744-299/300 Near the Galactic Center
Abstract
We present a study of two X-ray bursters in the Galactic Center field with the ART-P telescope onboard GRANAT. During 1990-1992 approximately 100 X-ray bursts were detected from the Galactic Center field and most of them were identified with the two persistent sources, A1742-294 and SLX1744-299/300. The burst recurrence times were found to be ~2.4 and ~4.6 hours, respectively, which is significantly shorter them was previously thought. We calculated the mean and maximum fluxes during the bursts and investigated their time profiles. We found that the shape of A1742-294 bursts correlates with the burst peak flux. The spectral analysis was carried out for the strongest burst, detected from A1742-294 on Oct 18, 1990.
