Investigating the properties of nearby young moving groups using GaiaDR3
Mamta Lad, Ujjwal Krishnan, Blesson Mathew +4
Moving groups, which are gravitationally unbound collections of stars spread over large portions of the sky, pose challenges to their identification. Analyzing the three-dimensiona…
A multi-epoch spectral and photometric study to understand the nature of the interesting Be star candidate HD 249179
Suman Bhattacharyya, Blesson Mathew, S Muneer +2
HD 249179, a B5 star with unclear classification as either a classical Be star or a high-mass X-ray binary (HMXB) system, is investigated using the first multi-epoch spectral and p…
Revealing the substellar population of IC 1396: A spectroscopic survey of brown dwarfs in the region
Belinda Damian, Jessy Jose, Aleks Scholz +7
We present a new spectroscopic view of the brown dwarf population in the young star-forming region IC 1396 and investigate the impact of environment on low-mass star formation. We…
Correlation Between Lunar Surface and Exospheric Sodium: Effects of Albedo-Driven Temperature on Multilayer Sodium Reservoirs Rather Than Surface Abundance Variations
A. Devaraj, S. Narendranath, Sreeja. S. Kartha +1
Sodium (Na) is a moderately volatile element in the lunar exosphere, released from the surface through thermal and non-thermal processes. We present a combined analysis of Chandray…
Non-Linear Solar EUV-Driven Sodium Release from the Lunar Surface: A Contrast to the Linear PSD Model
A Devaraj, S Narendranath, Sreeja S Kartha +7
The correlation between solar Extreme Ultra-Violet (EUV) radiation above 8.8 eV and the release of sodium from the lunar surface via photon-stimulated desorption (PSD) is investiga…
Probing the resolved K-S relation in nearby galaxies: Insights from UVIT and ALMA observations
K Sruthi, Sreeja S Kartha, Blesson Mathew +3
This study examines the resolved Kennicutt Schmidt (rKS) relation, defined as the connection between the star formation rate surface density (Sigma SFR) and the molecular gas mass…
