  • Clustering of low-mass stars around Herbig Be star IL Cep – evidence of ‘Rocket Effect’ using Gaia EDR3 ? 
    Arun, R; Mathew, B; Maheswar, G; Baug, Tapas; Kartha, S. S; Selvakumar, G; Manoj, P; Shridharan, B; Anusha, R; Narang, Mayank (Oxford University Press on behalf of the Royal Astronomical Society, 2021-10)
    We study the formation and the kinematic evolution of the early-type Herbig Be star IL Cep and its environment. The young star is a member of the Cep OB3 association, at a distance of 798 ± 9 pc, and has a ‘cavity’ ...
  • Discovery of an M-type companion to the Herbig Ae Star V1787 Ori 
    Arun, R; Mathew, B; Sridharan, R; Manoj, P; Narang, M; Kartha, S. S; Maheswar, G (Oxford University Press on behalf of the Royal Astronomical Society, 2021-02)
    The intermediate-mass Herbig Ae star V1787 Ori is a member of the L1641 star-forming region in the Orion A molecular cloud. We report the detection of an M-type companion to V1787 Ori at a projected separation of 6.66 arcsec ...
  • Emission line star catalogues post-Gaia DR3: A validation of Gaia DR3 data using the LAMOST OBA emission catalogue 
    Shridharan, B; Mathew, B; Bhattacharyya, S; Robin, T; Arun, R; Kartha, S. S; Manoj, P; Nidhi, S; Maheswar, G; Paul, K. T; Narang, M; Himanshu, T (EDP Sciences, 2022-12)
    Aims. Gaia Data Release 3 (DR3) and further releases have the potential to identify and categorise new emission-line stars in the Galaxy. We perform a comprehensive validation of astrophysical parameters from Gaia DR3 ...
