Structures present on the accretion disk aroound compact objects lead to absorption signatures from many highly-ionized species and also neutral material that usually are responsible for the X-ray dips occurring at different orbital epochs. XTE J1710-281 is a transient Low Mass X-ray Binary (LMXB) with an inclination angle i ~75-80 degrees. It shows periodic X-ray eclipses every 3.28 hours. This LMXB also exhibits X-ray intensity dips that are phase-locked, indicative of obscuration by a thickened accretion disk at the outer regions. We have carried out a multi-mission timing and spectral study of this dipping source using Chandra and Suzaku archival data. We have obtained timing signatures that indicate the presence of accretion disk structures that may be evolving at orbital times-scales of a few hours. We also detect a number of interesting features in the Suzaku spectra. We also present the similarities and differences in the the timing and spectral properties of this source and another well-studied eclipsing source, EXO 0748-676. |
