X-ray observation of newly discovered transient XTE J1748-288 by the Indian X-ray astronomy experiment

Abstract

The observations of X-ray transient XTE J1748-288 were made in the energy band 2 - 18 keV with the Indian X-ray astronomy experiment (IXAE) during 1998, June 14-25 with total useful exposure of 27,100 second for 1 sec integration mode and 15,440 sec for the 0.1 sec mode. The X-ray light curves showed no significant intensity variations on short time scale (< 10s). The power density spectrum obtained from timing analysis of the data show no quasi-periodic oscillations in the frequency range of 0.001 Hz to 5 Hz. From the observed X-ray characteristics it is difficult to infer the nature of the X-ray source.
