AstroSat observations of the Be/X-ray binary XTE J1946+274 during 2018 and 2021 outbursts
Amar Deo Chandra, Jayashree Roy, P. C. Agrawal
We present the timing and spectral studies of the Be/X-ray binary XTE J1946+274 during its 2018 and 2021 giant outbursts using observations with the SXT and the LAXPC instruments o…
Improved background model for the Large Area X-ray Proportional Counter (LAXPC) instrument on-board AstroSat
H. M. Antia, P. C. Agrawal, Tilak Katoch +3
We present an improved background model for the Large Area X-ray Proportional Counter (LAXPC) detectors on-board AstroSat. Because of the large collecting area and high pressure, t…
Detection of nearly periodic spin period reversals in Vela X-1 on long time-scales: inkling of solar-like cycle in the donor star?
Amar Deo Chandra, Jayashree Roy, P. C. Agrawal +1
We explore the long-term evolution of the spin period of the High Mass X-ray Binary (HMXB) pulsar Vela X-1 over a period of 46 yr. Our analysis indicates nearly periodic variations…
LAXPC instrument onboard AstroSat: Five exciting years of new scientific results specially on X-ray Binaries
J. S. Yadav, P. C. Agrawal, Ranjeev Misra +3
With its large effective area at hard X-rays, high time resolution and having co-aligned other instruments, AstroSat/LAXPC was designed to usher in a new era in rapid variability s…
Large Area X-ray Proportional Counter (LAXPC) in Orbit Performance : Calibration, background, analysis software
H. M. Antia, P. C. Agrawal, Dhiraj Dedhia +8
The Large Area X-ray Proportional Counter (LAXPC) instrument on-board AstroSat has three nominally identical detectors for timing and spectral studies in the energy range of 3--80…
AstroSat observations of eclipsing high mass X-ray binary pulsar OAO 1657-415
Gaurava K. Jaisawal, Sachindra Naik, Prahlad R. Epili +3
We present the results obtained from analysis of two AstroSat observations of the high mass X-ray binary pulsar OAO 1657-415. The observations covered 0.681-0.818 and 0.808-0.968 p…
