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…
Dust Reverberation Mapping of Z229-15
Amit Kumar Mandal, Suvendu Rakshit, C. S. Stalin +6
We report results of the dust reverberation mapping (DRM) on the Seyfert 1 galaxy Z229-15 at z = 0.0273. Quasi-simultaneous photometric observations for a total of 48 epochs were a…

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…
In search of radio emission from exoplanets: GMRT observations of the binary system HD~41004
Mayank Narang, Manoj P, C. H. Ishwara Chandra +6
This paper reports Giant Metrewave Radio Telescope (GMRT) observations of the binary system HD 41004 that are among the deepest images ever obtained at 150~MHz and 400 MHz in the s…
Discovery of an M-type Companion to the Herbig Ae Star V1787 Ori
R. Arun, Blesson Mathew, Sridharan Rengaswamy +4
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…
