  • Atmospheric mass-loss of extrasolar planets orbiting magnetically active host stars 
    Lalitha, S; Schmitt, J. H. M. M; Dash, S (Oxford University Press on behalf of the Royal Astronomical Society, 2018-06)
    Magnetic stellar activity of exoplanet hosts can lead to the production of large amounts of high-energy emission, which irradiates extrasolar planets, located in the immediate vicinity of such stars. This radiation is ...
  • Characterization of X-ray flare properties of AB Dor 
    Lalitha, S (International Astronomical Union, 2015-08)
    The strong similarities between the flares observed on the Sun and in low mass stars has raised question regarding dynamo in these stars. Using the Sun as a prototype, one may be able to address this. In this paper, we ...
  • X-Ray and Ultraviolet Flares on AT Microscopii Observed by AstroSat 
    Kuznetsov, A. A; Karakotov, R. R; Chandrashekhar, K; Banerjee, D (IOP Publishing, 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 ...
