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…

B. Kumar, R. Sagar, J. Melnick
We present CCD photometric and mass function study of 9 young Large Magellanic Cloud star clusters namely NGC 1767, NGC 1994, NGC 2002, NGC 2003, NGC 2006, SL 538, NGC 2011, NGC 20…
On the highly reddened members in 6 young galactic star clusters - a multiwavelength study
Brijesh Kumar, Ram Sagar, B. B. Sanwal +1
The spectral and reddening properties of 211 highly reddened proper motion members with mag in 6 young galactic star clusters are investigated using low resolution spectro…
Discovery of unusual pulsations in the cool, evolved Am stars HD 98851 and HD 102480
Santosh Joshi, V. Girish, R. Sagar +6
The chemically peculiar (CP) stars HD 98851 and HD 102480 have been discovered to be unusual pulsators during the ``Naini Tal Cape Survey'' programme to search for pulsational vari…
