Optical and X-ray studies of Be/X-ray binary 1A 0535+262 during its 2020 giant outburst
Birendra Chhotaray, Gaurava K. Jaisawal, Neeraj Kumari +3
We report results obtained from the optical and X-ray studies of the Be/X-ray binary 1A 0535+262/HD 245770 during the 2020 October giant X-ray outburst, using the 1.2 m telescope a…
Nanoflare Heating of the Solar Corona Observed in X-rays
Vishal Upendran, Durgesh Tripathi, N. P. S. Mithun +2
The existence of the million-degree corona above the cooler photosphere is an unsolved problem in astrophysics. Detailed study of quiescent corona that exists regardless of the pha…
Near-Earth Interplanetary Coronal Mass Ejections and Their Association with DH Type II Radio Bursts During Solar Cycles 23 and 24
Binal D. Patel, Bhuwan Joshi, Kyung-Suk Cho +2
We analyse the characteristics of interplanetary coronal mass ejections (ICMEs) during Solar Cycles 23 and 24. The present analysis is primarily based on the near-Earth ICME catalo…
Swift and XMM-Newton observations of an RS CVn type eclipsing binary SZ Psc: Superflare and coronal properties
Subhajeet Karmakar, Sachindra Naik, Jeewan C. Pandey +1
We present an in-depth study of a large and long duration (1.3 days) X-ray flare observed on an RS CVn type eclipsing binary system SZ Psc using observations from Swift observat…
Magnetohydrodynamics evolution of three-dimensional magnetic null in NOAA active region 11515 initiated using non-force-free field extrapolation
Sanjay Kumar, Avijeet Prasad, Ranadeep Sarkar +1
Magnetohydrodynamics simulation of active region NOAA 11515 is performed to examine the initiation of the M5.6 flaring event that starts around 10:43 UT on 2012 July 2. The simulat…
Soft X-ray Spectral Diagnostics of Multi-thermal Plasma in Solar Flares with Chandrayaan-2 XSM
N. P. S. Mithun, Santosh V. Vadawale, Giulio Del Zanna +7
Spectroscopic observations in X-ray wavelengths provide excellent diagnostics of the temperature distribution in solar flare plasma. The Solar X-ray Monitor (XSM) onboard the Chand…
