Discovery of a short orbital period in the Supergiant Fast X-ray Transient IGR J16479–4514
We report here the discovery of a 3.32 d orbital period in the Supergiant Fast X-ray Transient (SFXT) source IGR J16479−4514. Using the long-term light curve of this source obtained with Swift Burst… Expand
Nature of the Soft Spectral Component in the X-ray Pulsars SMC X-1 and LMC X-4
- B. Paul, F. Nagase, T. Endo, T. Dotani, J. Yokogawa, M. Nishiuchi
- Physics
- 16 July 2002
We present here the results of an investigation of the pulse averaged and pulse phase resolved energy spectra of two high luminosity accretion powered X-ray pulsars SMC X-1 and LMC X-4 made with… Expand
New measurements of orbital period change in Cygnus X-3
- N. S. Singh, S. Naik, +9 authors Mumbai
- Physics
- 10 June 2002
The nonlinear nature of the binary ephemeris of Cygnus X-3 indicates either a change in the orbital period or an apsidal motion of the orbit. We have made extended observations of Cygnus X-3 with the… Expand
Apsidal motion in 4U 0115+63 and orbital parameters of 2S 1417−624 and V0332+53
- H. Raichur, B. Paul
- Physics
- 21 August 2010
Be/X-ray binary pulsars have wide eccentric orbits and hence the angle of periastron of the orbit is very well defined in these sources. The presence of an X-ray pulsar allows for accurate… Expand
X-ray Spectroscopy of the High Mass X-ray Binary Pulsar Centaurus X-3 over its Binary Orbit
- S. Naik, B. Paul, +6 authors Sadashivnagar
- Physics
- 2 June 2011
We present a comprehensive spectral analysis of the high mass X-ray binary (HMXB) pulsar Centaurus X-3 with the Suzaku observatory covering nearly one orbital period. The light curve shows the… Expand
New measurement of orbital and spin period evolution of the accretion disc corona source 4U 1822−37
4U 1822-37 is a low mass X-ray binary (LMXB) system with an accretion disc corona. It is one of the very few LMXBs that shows narrow X-ray eclipses and small amplitude pulsations of the neutron star.… Expand
X-ray properties of the transient pulsar 3A 0535+262 in quiescence
- U. Mukherjee, B. Paul
- Physics
- 27 October 2004
We present the timing and spectral properties of the transient Be/X-ray binary pulsar 3A 0535+262 during quiescence using three observations with the narrow field imaging instruments (NFI) of… Expand
Different types of X-ray bursts from GRS 1915+105 and their origin
- J. S. Yadav, A. R. Rao, P. C. Agrawal, B. Paul, S. Seetha, K. Kasturirangan
- Physics
- 6 January 1999
We report X-ray observations of the Galactic X-ray transient source GRS 1915+105 with the pointed proportional counters of the Indian X-ray Astronomy Experiment (IXAE) onboard the Indian satellite… Expand
Phase-resolved X-ray polarimetry of the Crab pulsar with the AstroSat CZT Imager
- S. Vadawale, T. Chattopadhyay, +14 authors S. Seetha
- Physics
- 2018
The Crab pulsar is a typical example of a young, rapidly spinning, strongly magnetized neutron star that generates broadband electromagnetic radiation by accelerating charged particles to near light… Expand
Pulse Characteristics of the X-Ray Pulsar 4U 1907+09
- K. Mukerjee, P. C. Agrawal, +4 authors K. Kasturirangan
- Physics
- 10 February 2001
The X-ray pulsar 4U 1907+09 was observed in the 2-18 keV energy band with the Indian X-Ray Astronomy Experiment (IXAE) during 1996 August and again in 1998 June. From the timing measurements, the… Expand
