Detection of the thermonuclear X-ray bursts and dips from the X-ray binary 4U 1323-62 with AstroSat/LAXPC
Yashpal Bhulla, Jayashree Roy, S. N. A Jaaffrey
Using data from the Large Area X-ray Proportional Counter (LAXPC) on the \textit{AstroSat} satellite, we observed the Type-1 thermonuclear X-ray bursts from the Low Mass X-ray Bina…
Comprehensive Spectral Analysis of Cyg X-1 using RXTE Data
Rizwan Shahid, R. Misra, S. N. A. Jaaffrey
We analyse a large number () pointed RXTE observations of Cyg X-1 and model the spectrum of each one. A subset of the observations for which there is simultaneous reliable m…
Spectropolarimetery of umbral fine structures from Hinode: Evidence for magnetoconvection
Lokesh Bharti, Chandan Joshi, S. N. A. Jaaffrey +1
We present spectropolarimetric analysis of umbral dots and a light bridge fragment that show dark lanes in G-band images. Umbral dots show upflow as well as associated positive Sto…
Enhanced Joule Heating in Umbral Dots
Chandan Joshi, Lokesh Bharti, S. N. A. Jaaffrey
We present a study of magnetic profiles of umbral dots (UDs) and its consequences on the Joule heating mechanisms. Hamedivafa (2003) studied Joule heating using vertical component…
Variable Quasi Periodic Oscillations during an outburst of the transient X-ray pulsar XTE J1858+034
U. Mukherjee, S. Bapna, H. Raichur +2
We have investigated the Quasi Periodic Oscillation (QPO) properties of the transient accreting X-ray pulsar XTE J1858+034 during the second outburst of this source in April-May 20…
