AstroSat Observations of the first Galactic ULX Pulsar Swift J0243.6+6124
Aru Beri, Sachindra Naik, K. P Singh +11
SwiftJ0243.6+6124, the first Galactic ultra-luminous X-ray pulsar, was observed during its 2017-2018 outburst with \emph{AstroSat} at both sub- and super-Eddington levels of accret…
Pulse Phase Variation of Cyclotron Line in HMXB 4U 1907+09 with ASTROSAT LAXPC
Varun, Pragati Pradhan, Chandreyee Maitra +2
We present timing and spectral analysis of data from an observation of the High Mass X-ray Binary pulsar 4U 1907+09 with the LAXPC instrument onboard AstroSat. The light curve cons…
Probing the Cyclotron line characteristics of 4U 1538-522 using AstroSat-LAXPC
Varun, Chandreyee Maitra, Pragati Pradhan +2
We report the first report on cyclotron line studies with the LAXPC instrument onboard AstroSat of the High mass X-ray Binary pulsar 4U 1538-52. During the observation of source wh…
-mode strengthening from a localized bipolar subsurface magnetic field
Nishant K. Singh, Harsha Raichur, Maarit J. Käpylä +3
Recent numerical work in helioseismology has shown that a periodically varying subsurface magnetic field leads to a fanning of the -mode, which emerges from the density jump at…
Understanding the nature of the intriguing source X Persei: A deep look with a Suzaku observation
Chandreyee Maitra, Harsha Raichur, Pragati Pradhan +1
We present detailed broadband timing and spectral analysis of the persistent, low luminosity and slowly spinning pulsar X Persei using a deep Suzaku observation of the source. The…
High-wavenumber solar -mode strengthening prior to active region formation
Nishant K. Singh, Harsha Raichur, Axel Brandenburg
We report a systematic strengthening of the local solar surface or fundamental -mode - days prior to the emergence of an active region (AR) in the same (corotating) locati…
