Quiescent and flaring states of three active stars: V834 Tau, LQ Hya, and BY Dra
Gurpreet Singh, Jeewan C. Pandey, Subhajeet Karmakar
We present a detailed X-ray study of the quiescent and flaring coronae of three active main-sequence K-type stars, V834 Tau, LQ Hya, and BY Dra, using \textit{XMM-Newton} observati…
AB Dor: Coronal imaging and activity cycles
Gurpreet Singh, Jeewan C. Pandey
Using long-term X-ray observations, we present the short-term and long-term X-ray variability analysis of the ultra-fast rotating active star AB Dor. Flaring events are common in X…
AstroSat investigation of X-ray flares on two active K-M systems: CC Eri and AB Dor
Subhajeet Karmakar, Jeewan C. Pandey, Nikita Rawat +2
We present an X-ray and UV investigation of five X-ray flares detected on two active systems, CC Eri and AB Dor, using the AstroSat observatory. The peak X-ray luminosities of the…
Study of the Energetic X-ray Superflares from the active fast rotator AB Doradus
Shweta Didel, Jeewan C. Pandey, A. K. Srivastava +1
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…
