  • Li Distribution, Kinematics, and Detailed Abundance Analysis among Very Metal-poor Stars in the Galactic Halo from the HESP-GOMPA Survey 
    Bandyopadhyay, A; Sivarani, T; Beers, Timothy C; Susmitha, A; Nayak, Prasanta K; Pandey, Jeewan C (American Astronomical Society, 2022-10-01)
    We present a study on the detailed elemental abundances of newly identified, bright, very metal-poor stars with the detection of lithium, initially observed as part of the SDSS/MARVELS pre-survey. These stars were selected ...
  • Optical and NIR spectroscopy of cool CEMP stars to probe the nucleosynthesis in low-mass AGB binary system 
    Susmitha, A; Ojha, D. K; Sivarani, T; Ninan, J. P; Bandyopadhyay, A; Surya, Arun; Unni, Athira (Oxford University Press on behalf of Royal Astronomical Society, 2021-09)
    We present the abundance analyses of seven carbon enhanced metal-poor (CEMP) stars to understand the origin of carbon in them. We used high-resolution optical spectra to derive abundances of various elements. We also used ...
  • Oxygen abundances of carbon-enhanced stellar population in the halo 
    Susmitha, A; Sivarani, T; Ojha, D. K; Ninan, Joe P; Bandyopadhyay, A; Surya, A; Athira, U (Springer, 2020-12)
    The large fraction of carbon-enhanced metal-poor (CEMP) stars at lower metallicities makes them an interesting class of objects to be probed further in greater detail. They show different abundance patterns of neutron-capture ...
  • TANSPEC: TIFR-ARIES Near-infrared Spectrometer 
    Sharma, Saurabh; Ojha, Devendra. K; Ghosh, Arpan; Ninan, Joe. P; Ghosh, Supriyo; Ghosh, Swarna. K; Manoj, P; Naik, Milind. B; D'Costa, Savio, L. A; Reddy, B. Krishna; Nanjappa, Nandish; Pandey, Rakesh; Sinha, Tirthendu; Panwar, Neelam; Susmitha, A; Kaur, Harmeen; Sahu, Sanjit; Bangia, Tarun; Poojary, Satheesha S; Jadhav, Rajesh. B; Bhagat, Shailesh. B; Meshram, Ganesh. S; Shah, Harshit; Rayner, John. T; Toome, Douglas. W; Sandimani, Pradeep. R (IOP Publishing Ltd on behalf of the Astronomical Society of the Pacific, 2022-08)
    We present the design and performance of the TANSPEC, a medium-resolution 0.55–2.5 μm cryogenic spectrometer and imager, now in operation at the 3.6 m Devasthal Optical Telescope (DOT), Nainital, India. The TANSPEC provides ...
