  • 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’ ...
  • Optical Spectroscopy of Classical Be Stars in Old Open Clusters 
    Jagadeesh, Madhu Kashyap; Mathew, Blesson; Paul, K. T; Banerjee, Gourav; Bhattacharyya, Suman; Anusha, R; Pramod Kumar, S (IOP Publishing, 2023-03)
    We performed the optical spectroscopy of 16 classical Be stars in 11 open clusters older than 100 Myr. Ours is the first spectroscopic study of classical Be stars in open clusters older than 100 Myr. We found that the Hα ...
  • Optical spectroscopy of Galactic field classical Be stars 
    Banerjee, G; Mathew, B; Paul, K. T; Subramaniam, A; Bhattacharyya, S; Anusha, R (Oxford University Press on behalf of the Royal Astronomical Society, 2021-01)
    In this study, we analyse the emission lines of different species present in 118 Galactic field classical Be stars in the wavelength range of 3800–9000 Å. We re-estimated the extinction parameter (AV) for our sample stars ...
  • Spectroscopic study of Herbig Ae/Be stars in the Galactic anti-centre region from LAMOST DR5 
    Nidhi, S; Mathew, Blesson; Shridharan, B; Arun, R; Anusha, R; Kartha, Sreeja S (Oxford University Press on behalf of Royal Astronomical Society, 2023-10)
    We study a sample of 119 Herbig Ae/Be stars in the Galactic anti-centre direction using the spectroscopic data from large sky area multi-object fiber spectroscopic telescope survey program. Emission lines of hydrogen ...
  • Study of transient nature of classical Be stars using multi-epoch optical spectroscopy 
    Banerjee, Gourav; Mathew, Blesson; Paul, K. T; Subramaniam, A; Balan, Anjusha; Bhattacharyya, Suman; Anusha, R; Moosa, Deeja; Dheeraj, C. S.; Charly, Aleeda; Raghu, Megha (Indian Academy of Sciences, 2022-12)
    Variability is a commonly observed property of classical Be stars (CBe) stars. In extreme cases, complete disappearance of the Hα emission line occurs, indicating a disc-less state in CBe stars. The disc-loss and reappearing ...
