Long term flux variations in Cen X-3: clues from flux dependent orbital modulation and pulsed fraction
H. Raichur, B. Paul
We have investigated the long term flux variation in Cen X-3 using orbital modulation and pulsed fraction in different flux states using observations made with the All Sky Monitor…
Orbital Evolution and orbital phase resolved spectroscopy of the HMXB pulsar 4U 1538-52 with RXTE-PCA and BeppoSAX
U. Mukherjee, H. Raichur, B. Paul +2
We report here results from detailed timing and spectral studies of the high mass X-ray binary pulsar 4U~1538--52 over several binary periods using observations made with the Rossi…
Variable Quasi Periodic Oscillations during an outburst of the transient X-ray pulsar XTE J1858+034
U. Mukherjee, S. Bapna, H. Raichur +2
We have investigated the Quasi Periodic Oscillation (QPO) properties of the transient accreting X-ray pulsar XTE J1858+034 during the second outburst of this source in April-May 20…
Accretion mode changes in Centaurus X-3
B. Paul, H. Raichur, U. Mukherjee
We report here discovery of the existence of two different accretion modes in the high mass X-ray binary pulsar Cen X-3 during its high states. The multiband X-ray light curves of…
