  • Evolution of magnetic activities in Late-type stars 
    Karmakar, Subhajeet (ARIES, Nainital, 2017-07)
  • A multiwavelength view of a classical T Tauri star CV Cha 
    Pandey, Jeewan Chandra; Karmakar, Subhajeet; Joshi, Arti; Sharma, Saurabh; Pandey, Shashi Bhushan; Pandey, Anil Kumar (Research in Astronomy and Astrophysics, 2019-01)
    Using long-term optical, ultraviolet (UV) and X-ray data, we present a study of a classical T Tauri star CV Cha. The V -band light curve obtained from the All Sky Automated Survey (ASAS) shows short as well as long-term ...
  • Phase-resolved XMM-Newton and swift observations of WR 25 
    Pandey, J. C.; Pandey, S. B.; Karmakar, Subhajeet (The American Astronomical Society, 2014-05-23)
    We present an analysis of long-term X-ray and optical observations of the Wolf–Rayet binary, WR 25. Using archival data from observations with the XMM-Newton and the Swift observatories, spanning over ∼10 yr, we show ...
  • 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 ...
  • An X-ray flare from 47 cas 
    Pandey, J. C.; Karmakar, Subhajeet (The American Astronomical Society, 2015-01-08)
    Using XMM-Newton observations, we investigate properties of a flare from the very active but poorly known stellar system 47 Cas. The luminosity at the peak of the flare is found to be 3.54 × 10 ³⁰ erg s⁻¹, which is ∼2 times ...
