  • Indigenous Development Software for the 90” Mirror coating plant, VBO 
    Arumugam, V (Indian Institute of Astrophysics, 2023-09-22)
    A Telescope is an instrument that aids in the observation of stellar and celestial objects. Mirrors are an important subsystem in the Telescope. Over a period, due to weathering effects, reflection efficiency of the mirrors ...
  • NTP Server and Weather Monitor for Kodaikanal Solar Observatory 
    Anand, M. N (Indian Institute of Astrophysics, 2023-06)
    We perceive time as a passage of events, a marker of change. In astronomy and astrophysics, we study events occurring over a short time (order of seconds) to long-term (a few years) variability. Accurate time stamping is ...
  • Forty Hypervelocity Stars from Gaia DR3 
    Parthasarathy, M (American Astronomical Society, 2024-04)
    Forty hypervelocity stars (HVS) are detected from a search for HVS in Gaia DR3 data whose G magnitudes are less than 17.0 and radial velocities are more +400 km s‑1. The Gaia DR3 astrophysical parameters and spectra indicate ...
  • A Selection of 23 Bright Hypervelocity Gaia DR3 Stars 
    Parthasarathy, M (American Astronomical Society, 2024-03)
    From the Gaia DR3 data twenty three bright hypervelocity stars that have Tycho catalogue numbers are presented. All these stars are of high galactic latitude and some may be galactic halo stars. All of them have accurate ...
  • A chemodynamical analysis of bright metal-poor stars from the HESP-GOMPA survey – indications of a non-prevailing site for light r-process elements 
    Bandyopadhyay, A; Beers, Timothy C; Ezzeddine, Rana; Sivarani, T; Nayak, Prasanta K; Pandey, Jeewan C; Saraf, Pallavi; Susmitha, A (Oxford University Press on behalf of Royal Astronomical Society, 2024-04)
    We present a comprehensive analysis of the detailed chemical abundances for a sample of 11 metal-poor, very metal-poor, and extremely metal-poor stars ([Fe/H] = −1.65 to [Fe/H] = −3.0) as part of the HESP-GOMPA (Galactic ...
