Study of the energetic X-ray superflares from the active fast rotator AB doradus

Didel, Shweta; Pandey, Jeewan C.; Srivastava, A. K.; Singh, Gurpreet (Monthly Notices of the Royal Astronomical Society, 2024-01)

We present the analyses of intense X-ray flares detected on the active fast rotator AB Dor using observations from the XMM– Newton. A total of 21 flares are detected, and 13 flares are analysed in detail. The total X-ray ...
Swift and XMM–Newton observations of an RS CVn-type eclipsing binary SZ Psc: superflare and coronal properties

Karmakar, Subhajeet; Naik, Sachindra; Pandey, Jeewan C.; Savanov, Igor S. (Monthly Notices of the Royal Astronomical Society, 2023-01)

We present an in-depth study of a large and long duration (>1.3 d) X-ray flare observed on an RS CVn-type eclipsing binary system SZ Psc using observations from Swift observatory. In the 0.35–10 keV energy band, the peak ...
X-Ray and Ultraviolet Flares on AT Microscopii Observed by AstroSat

Kuznetsov, A. A.; Karakotov, R. R.; Chandrashekhar, K.; Banerjee, D. (Research in Astronomy and Astrophysics, 2023-01)

We present observations of the active M-dwarf binary AT Mic (dM4.5e+dM4.5e) obtained with the orbital observatory AstroSat. During 20 ks of observations, in the far-ultraviolet (130–180 nm) and soft X-ray (0.3–7 keV) spectral ...
