Study of the Balmer decrements for Galactic classical Be stars using the Himalayan Chandra Telescope of India
Gourav Banerjee, Blesson Mathew, Suman Bhattacharyya +3
In a recent study, Banerjee et al. (2021) produced an atlas of all major emission lines found in a large sample of 115 Galactic field Be stars using the 2-m Himalayan Chandra Teles…
Chandra X-ray Analysis of Herbig Ae/Be Stars
Hema Anilkumar, Blesson Mathew, V. Jithesh +4
Herbig Ae/Be (HAeBe) stars are intermediate-mass pre-main sequence stars, characterized by infrared excess and emission lines. They are observed to emit X-rays, whose origin is a m…
Optical Spectroscopy of Classical Be Stars in Old Open Clusters
Madhu Kashyap Jagadeesh, Blesson Mathew, K. T. Paul +4
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…
UVIT/AstroSat observation of TW Hya
Prasanta K. Nayak, Mayank Narang, P. Manoj +7
The paper demonstrates the spectroscopic and photometric capabilities of the Ultra-Violet Imaging Telescope (UVIT) to study T-Tauri stars (TTSs). We present the first UVIT/Far-UV (…
Identifying the population of T-Tauri stars in Taurus: UV-optical synergy
Prasanta K. Nayak, Mayank Narang, Manoj Puravankara +9
With the third data release of the Gaia mission DR3 with its precise photometry and astrometry, it is now possible to study the behaviour of stars at a scale never seen befo…
Optical spectroscopy of Gaia detected protostars with DOT: can we probe protostellar photospheres?
Mayank Narang, Manoj Puravankara, Himanshu Tyagi +7
Optical spectroscopy offers the most direct view of the stellar properties and the accretion indicators. Standard accretion tracers, such as , , and, Ca II triplet lines, a…
