Spectroscopic study of Herbig Ae/Be stars in the Galactic Anti-center region from LAMOST DR5
S. Nidhi, Blesson Mathew, B. Shridharan +3
We study a sample of 119 Herbig Ae/Be stars in the Galactic anti-center direction using the spectroscopic data from Large sky Area Multi-Object fiber Spectroscopic Telescope (LAMOS…
Study of the transient nature of classical Be stars using multi-epoch optical spectroscopy
Gourav Banerjee, Blesson Mathew, K. T. Paul +8
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…
Identification of emission-line stars in transition phase from pre-main sequence to main sequence
Suman Bhattacharyya, Blesson Mathew, Gourav Banerjee +3
Pre-main sequence (PMS) stars evolve into main sequence (MS) phase over a period of time. Interestingly, we found a scarcity of studies in existing literature that examines and att…
Clustering of low mass stars around Herbig Be star IL Cep -- Evidence of "Rocket Effect" using Gaia EDR3 ?
R. Arun, Blesson Mathew, G. Maheswar +7
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…
Identification of new Classical Ae stars in the Galaxy using LAMOST DR5
R. Anusha, Blesson Mathew, B. Shridharan +6
We report the first systematic study to identify and characterize a sample of classical Ae stars in the Galaxy. The spectra of these stars were retrieved from the A-star catalog us…
Optical spectroscopy of Galactic field Classical Be stars
Gourav Banerjee, Blesson Mathew, K. T. Paul +3
In this study, we analyze 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 ext…
