An investigation of the "10 keV feature" in the spectra of Accretion Powered X-ray Pulsars with NuSTAR
Hemanth Manikantan, Biswajit Paul, Vikram Rana
Some of the accreting X-ray pulsars are reported to exhibit a peculiar spectral feature at 10 keV, known as the "10 keV feature". The feature has been characterized as either…
X-ray reprocessing: Through the eclipse spectra of low mass X-ray binaries with XMM-Newton
Nafisa Aftab, Biswajit Paul
Eclipsing X-ray binaries make an ideal condition to study reprocessed X-rays, as the X-rays detected during eclipse are purely reprocessed while the much brighter primary X-rays ar…
4U 1626-67 Returns to Spin-Down: Timing features toe the line
Rahul Sharma, Chetana Jain, Biswajit Paul
We present a comprehensive analysis of X-ray pulsar 4U 1626-67 during its current spin-down (2SD) state, following a recent torque reversal. Since its discovery, this ultra-compact…
Clumpy wind studies and the non-detection of cyclotron line in OAO 1657-415
Pragati Pradhan, Carlo Ferrigno, Biswajit Paul +11
Winds of massive stars are suspected to be inhomogeneous (or clumpy), which biases the measures of their mass loss rates. In High Mass X-ray Binaries (HMXBs), the compact object ca…
Changes in the distribution of circum-binary material around the HMXB GX 301-2 during a rapid spin-up episode of the neutron star
Hemanth Manikantan, Biswajit Paul, Kinjal Roy +1
Some accretion powered X-ray pulsars with supergiant companion stars undergo occasional rapid spin-up episodes that last for weeks to a few months. We explore the changes in the ac…
Broadband mHz QPOs and spectral study of LMC X4 with AstroSat
Rahul Sharma, Chetana Jain, Ketan Rikame +1
We report the results of broadband timing and spectral analysis of data from an AstroSat observation of the High Mass X-ray binary LMC X4. The Large Area X-ray Proportional Coun…
