Insight-HXMT Spectral and Timing Studies of a Giant Outburst in RX J0440.9+4431
Prahlad R. Epili, Wei Wang
The Be/X-ray binary pulsar RX J0440.9+4431 underwent a giant outburst in late 2022 and lasted three months. The Insight-HXMT has observed this source at several instances of the en…
AstroSat and Insight-HXMT observations of the long-period X-ray pulsar 4U 2206+54
Prahlad R. Epili, Wei Wang
We report the timing and spectral studies of the accreting X-ray pulsar 4U 2206+54 using astrosat and hxmt observations taken in 2016 and 2020 respectively. X-ray pulsations from t…
Evidence for a cyclotron absorption line and spectral transition in EXO 2030+375 during 2021 giant outburst
Wen Yang, Wei Wang, Prahlad R. Epili
Based on HXMT observations of EXO 2030+375 during its 2021 giant outburst, we report the analysis of pulse variations and the broadband X-ray spectrum, and find the presence of a p…
Timing and spectral variability of high mass X-ray pulsar GX 301--2 over orbital phases observed by Insight-HXMT
Y. Z. Ding, W. Wang, P. R. Epili +7
We report the orbital X-ray variability of high mass X-ray binary (HMXB) GX301--2. GX301--2 undergone a spin up process in 2018--2020 with the period evolving from 685 s to…
Accretion Torque Reversals in GRO J1008-57 Revealed by Insight-HXMT
W. Wang, Y. M. Tang, Y. L. Tuo +92
GRO J1008-57, as a Be/X-ray transient pulsar, is considered to have the highest magnetic field in known neutron star X-ray binary systems. Observational data of the X-ray outbursts…
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…
