X-ray Observations of Grs 1915+105
1. Spectral analysis of simultaneous ROSAT/BATSE data After the discovery of GRS 1915+105 (Castro-Tirado et al. 1992) we obtained pointed ROSAT observations every six months (12 until now). The flux in the ROSAT (0.1–2.4 keV) band is strikingly different from the simultaneous BATSE (25–50 keV) flux which was obtained by integrating the best fit power law (Fig. 1). Motivated by the different int...
متن کاملRapid X - ray variability of the superluminal source GRS 1915
The superluminal X-ray transient source GRS 1915+105 was observed during July 20-29, 1996 with the Indian X-ray Astronomy Experiment (IXAE) on the Indian satellite IRS-P3 launched on March 21, 1996 from Shriharikota Range in India. During our observations covering the energy band 2-18 keV, we have seen strong erratic intensity variations on time scale of 0.1s 10s. Quasi Periodic Oscillations (Q...
متن کاملGRS 1009 – 45 ( = X - Ray Nova Velorum 1993 ) : a ‘ hybrid ’ soft X - ray transient ? ?
High–time resolution photometry, performed from November 17 to December 11, 1993, on GRS 1009–45 (=XRay Nova Velorum 1993) reveals a V light modulation with a periodicity of 0.1996 days (∼ 4h.79). If the nature of this modulation is similar to that of the superhumps seen in SU UMa dwarf novae during superoutbursts, then the object would have the shortest orbital period among Soft X-Ray Transien...
متن کاملX-ray Bursts from the Galactic X-ray Transient Source Grs 1915+105
We have analyzed publicly available RXTE/PCAs archival data of GRS 1915+105 during its burst/flaring state. The burst cycle ranges from 30 to 1300 s. These bursts are different from the type I and type II classical bursts seen in Low Mass X-ray Binaries (LMXBs) in terms of their temporal and spectral properties. We have classified these bursts on the basis of properties observed during the quie...
