Open Cluster Study Using I:Membership and Cluster Properties
Anindya Ganguly, Prasanta K. Nayak, Sourav Chatterjee
Star clusters are interesting laboratories to study star formation, single and binary stellar evolution, and stellar dynamics. We have used the exquisite data from 's data re…
uGMRT Survey of EXoplanets Around M-dwarfs (GS-EXAM): Radio observations of GJ 1151
Mayank Narang, Manoj Puravankara, H. K. Vedantham +9
Coherent radio emission with properties similar to planetary auroral signals has been reported from GJ 1151, a quiescent, slow-rotating mid-M star, by the LOFAR Two-metre (120-170…
Demography of stellar radio population within 500 pc: A VLASS-Gaia DR3 study
Ayanabha De, Mayank Narang, Manoj Puravankara +5
In this work, we have carried out a systematic analysis of the VLASS quick look catalogs together with \textit{Gaia DR3} to identify the optical counterparts of 3~GHz radio emitter…
UVIT Study of the MAgellanic Clouds (U-SMAC) II. A Far-UV catalog of the Small Magellanic Cloud: Morphology and Kinematics of young stellar population
Sipra Hota, Annapurni Subramaniam, Prasanta K. Nayak +1
The Small Magellanic Cloud (SMC) is an irregular dwarf galaxy that has recently undergone an interaction with the Large Magellanic Cloud. The young massive stars in the SMC formed…
Host star properties of hot, warm and cold Jupiters in the solar neighborhood from \textit{Gaia} DR3: clues to formation pathways
Bihan Banerjee, Mayank Narang, P. Manoj +5
Giant planets exhibit diverse orbital properties, hinting at their distinct formation and dynamic histories. In this paper, using DR3, we investigate if and how the…
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 (…
Simultaneous FUV and NUV observations of T Tauri stars with UVIT/AstroSat: probing accretion process in young stars
Prasanta K. Nayak, Mayank Narang, P. Manoj +4
We present results from simultaneous FUV and NUV observations of T-Tauri stars (TTSs) in the Taurus molecular cloud with UVIT/AstroSat. This is the very first UVIT study of TTSs. F…
A chemodynamical analysis of bright metal-poor stars from the HESP-GOMPA survey -- Indications of a non-prevailing site for light r-process elements
Avrajit Bandyopadhyay, Timothy C Beers, Rana Ezzeddine +5
We present a comprehensive analysis of the detailed chemical abundances for a sample of 11 metal-poor, very metal-poor and extremely metal-poor stars ([Fe/H] = -1.65 to [Fe/H] = -3…
A uGMRT search for radio emission from planets around evolved stars
Mayank Narang, P. Manoj, Ishwara Chandra +8
In this work, we present the results from a study using the Giant Meterwave Radio Telescope (GMRT) to search for radio {emission} from planets around three evolved stars namely …
Spatio-temporal map of star clusters in the Magellanic Clouds using Gaia: Synchronized peaks and radial shrinkage of cluster formation
S. R. Dhanush, A. Subramaniam, Prasanta K. Nayak +1
We present a detailed view of cluster formation (CF) to trace the evolution and interaction history of the Magellanic Clouds (MCs) in the last 3.5 Gyr. Using the \textit{Gaia} DR3…
