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 ...
X-ray confirmation of the intermediate polar IGR J16547-1916

Joshi, A.,et.al.; Pandey, J. C.; Rawat, N. (Astronomy & Astrophysics, 2022-01)

Using X-ray observations from the NuSTAR and Swift satellites, we present temporal and spectral properties of an intermediate polar (IP) IGR J16547-1916. A persistent X-ray period at ∼546 s confirming the optical spin ...
