摘 要:Using data from the Large Area X-ray Proportional Counter(LAXPC)on the AstroSat satellite,we observed Type-1 thermonuclear X-ray bursts from the low mass X-ray binary neutron star 4 U *** of 4 U 1323-62 that were carried out during the performance verification phase of the AstroSat satellite indicated six thermonuclear X-ray bursts in a total effective exposure of^49.5 ks for about two consecutive *** time of the detected thermonuclear bursts is in accordance with the orbital period of the source,~9400 ***,the light curve of 4 U 1323-62 revealed the presence of two *** present the results from time-resolved spectroscopy performed during all of the six X-ray bursts and also report the detection of a known low frequency quasi-periodic oscillation(LFQPO)at^1 Hz from the ***,any evidence of kilohertz QPO was not *** have shown the burst profile at different energy *** a distance of 10 kpc,we observed a mean flux of^1.8×10^-9 erg cm^2 s^-*** radius of the blackbody is found to be highly consistent with the blackbody temperature and the blackbody flux of the bursts.
