Chandra and XMM-Newton observations of the low-luminosity X-ray pulsators SAX J1324.4-6200 and SAX J1452.8-5949
Ramanpreet Kaur, Rudy Wijnands, Alessandro Patruno +5
We present results from our Chandra and XMM-Newton observations of two low-luminosity X-ray pulsators SAX J1324.4-6200 and SAX J1452.8-5949 which have spin-periods of 172 s and 437…
Multiwavelength study of the transient X-ray binary IGR J01583+6713
Ramanpreet Kaur, Biswajit Paul, Brijesh Kumar +1
We have investigated multiband optical photometric variability and stability of the H line profile of the transient X-ray binary IGR J01583+6713. We set an upper limit of 0.05 m…
A study of the long term evolution of quasi periodic oscillations in the accretion powered X-ray pulsar 4U 1626-67
Ramanpreet Kaur, Biswajit Paul, Brijesh Kumar +1
We report here a study of the long term properties of Quasi Periodic Oscillations (QPO) in an unusual accreting X-ray pulsar, 4U 1626--67. This is a unique accretion powered X-ray…
Quasi periodic oscillations in XTE J0111.2--7317, highest frequency among the HMXB pulsars
Ramanpreet Kaur, Biswajit Paul, Harsha Raichur +1
We report here discovery of Quasi Periodic Oscillations (QPOs) in the High Mass X-ray Binary (HMXB) Pulsar XTE J0111.20-7317 during a transient outburst in this source in December…
