  • Carbon Abundance of Stars in the LAMOST-Kepler Field 
    Athira Unni; Narang, Mayank; Sivarani, T; Puravankara, Manoj; Banyal, R. K; Surya, Arun; Rajaguru, S. P; Swastik, C (American Astronomical Society, 2022-11-01)
    The correlation between host star iron abundance and the exoplanet occurrence rate is well established and arrived at in several studies. Similar correlations may be present for the most abundant elements, such as carbon ...
  • Galactic Chemical Evolution of Exoplanet Hosting Stars: Are High-mass Planetary Systems Young? 
    Swastik, C; Banyal, R. K; Narang, Mayank; Manoj, P; Sivarani, T; Rajaguru, S. P; Athira Unni; Banerjee, Bihan (American Astronomical Society, 2022-08-01)
    The imprints of stellar nucleosynthesis and chemical evolution of the galaxy can be seen in different stellar populations, with older generation stars showing higher α-element abundances and the later generations ...
  • Hanle echelle spectrograph: design and performance 
    Sriram, S; Amit Kumar; Arun Surya; Sivarani, T; Giridhar, S; Kathiravan, S; Anand, M. N; Jones, D; Grobler, D; Jakobsson, R; Anantha, Ch; Athira Unni; Angchuk, D; Tsewang, D; Gyalson, T (SPIE-The International Society for Optical Engineering, 2018-07-06)
    Hanle echelle spectrograph (HESP) is a high resolution, bench mounted, fiber-fed spectrograph at visible wavelengths. The instrument was recently installed at the 2m Himalayan Chandra Telescope (HCT), located at Indian ...
