Unveiling the Nature of Superorbital Modulation of SMC X-1 using NinjaSat
Chin-Ping Hu, Naoyuki Ota, Takuya Takahashi +13
We report a long-term, high-cadence timing and spectral observation of the X-ray pulsar SMC X-1 using NinjaSat, a 6U CubeSat in low-Earth orbit, covering nearly a full superorbital…
XMM-Newton view of pulsating iron fluorescent emission from Centaurus X3
Kinjal Roy, Hemanth Manikantan, Biswajit Paul
Cen X-3 is a bright, high-mass X-ray binary pulsar. We present a pulse phase-resolved X-ray spectral analysis of data from an archival XMM-Newton observation of Cen X-3 taken durin…
Luminosity dependent cyclotron line in Swift J1626.6-5156
Binay Rai, Biswajit Paul, Mohammed Tobrej +3
We studied the timing and spectral properties of the Be/X-ray pulsar Swift J1626.6-5156 using the \emph{NICER} observations of its 2021 outburst. The most important observation is…
Comprehensive broadband study of accreting neutron stars with Suzaku: Is there a bi-modality in the X-ray spectrum?
Pragati Pradhan, Biswajit Paul, Enrico Bozzo +2
We present a broadband spectral analysis of accreting neutron stars using data from XIS and PIN onboard \emph{Suzaku}. From spectral fits of these sources with a single continuum m…
Detection of a cyclotron line in SXP 15.3 during its 2017 outburst
Chandreyee Maitra, Biswajit Paul, Frank Haberl +1
We report the results of AstroSat and NuSTAR observations of the Be/X-ray binary pulsar SXP 15.3 in the Small Magellanic Cloud during its outburst in late 2017, when the source rea…
Is 4U 0114+65 an eclipsing HMXB?
P. Pradhan, B. Paul, B. C. Paul +2
We present the pulsation and spectral characteristics of the HMXB 4U 0114+65 during a \emph{Suzaku} observation covering the part of the orbit that included the previously known lo…
Variations in the pulsation and spectral characteristics of OAO 1657-415
Pragati Pradhan, Chandreyee Maitra, Biswajit Paul +2
We present broad-band pulsation and spectral characteristics of the accreting X-ray pulsar OAO 1657--415 with a 2.2 d long \emph{Suzaku} observation carried out covering its orbita…
