Detection of the thermonuclear X-ray bursts and dips from the X-ray binary 4U 1323-62 with AstroSat/LAXPC

Using data from the Large Area X-ray Proportional Counter (LAXPC) on the \textit{AstroSat} satellite, we observed the Type-1 thermonuclear X-ray bursts from the Low Mass X-ray Binary Neutron Star 4U 1323-62. The observations of 4U 1323-62 were carried out during the performance verification phase of the \textit{AstroSat} satellite showed six thermonuclear X-ray bursts in a total effective exposure of $\sim$ 49.5 ks for about two consecutive days. Recurrence time of the detected thermonuclear bursts is in accordance with the orbital period of the source $\sim$ 9400 seconds. Moreover, the light curve of 4U 1323-62 revealed the presence of two dips. We presented 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 $\sim$ 1 Hz, from the source. However, any evidence of kilohertz QPO was not found. We have shown the burst profile at different energy ranges. Assuming a distance of 10 kpc, we observed a mean flux $\sim$ 1.8 $\times$ $10^{-9}$ erg $cm^2$ $s^{-1}$. The radius of the blackbody is found to be highly consistent with the blackbody temperature and the blackbody flux of the bursts.
