Orbital Phase Spectroscopy of four High Mass X-ray Binary Pulsars to Study the Stellar Wind of the Companion
Sachindra Naik, Uddipan Mukherjee, Biswajit Paul +1
Our work focuses on a comprehensive orbital phase dependent spectroscopy of the four High Mass X-ray Binary Pulsars (HMXBPs) 4U 1538-52, GX 301-2, OAO 1657-415 & Vela X-1. We hereb…
Near Infrared Observations of the novae V2491 Cygni and V597 Puppis
Sachindra Naik, D. P. K. Banerjee, N. M. Ashok
We present results obtained from near-infrared JHK spectroscopic observations of novae V2491 Cyg and V597 Pup in the early declining phases of their 2007 and 2008 outbursts respect…
Enhanced p-Mode Absorption seen near the Sunspot Umbral-Penumbral Boundary
Shibu K. Mathew
We investigate p-mode absorption in a sunspot using SOHO/MDI high-resolution Doppler images. The Doppler power computed from a three and a half hour data set is used for studying t…
Multi-color Optical Variability of the TeV Blazar Mrk 501 in the Low-State
A. C. Gupta, W. G. Deng, U. C. Joshi +2
We report results based on the monitoring of the BL Lac object Mrk 501 in the optical (B, V and R) passbands from March to May 2000. Observations spread over 12 nights were carried…
