Decoding the compositions of four bright -process-enhanced stars
Pallavi Saraf, Carlos Allende Prieto, Thirupathi Sivarani +3
There has been a concerted effort in recent years to identify the astrophysical sites of the -process that can operate early in the Galaxy. The discovery of many -process-enh…
Globular Cluster UVIT legacy Survey (GlobUleS) III. Omega Centauri in Far-Ultraviolet
Deepthi S. Prabhu, Annapurni Subramaniam, Snehalata Sahu +21
We present the first comprehensive study of the most massive globular cluster Omega Centauri in the far-ultraviolet (FUV) extending from the center to ~ 28% of the tidal radius usi…
Li distribution, kinematics and detailed abundance analysis among very metal-poor stars in the Galactic halo from the HESP-GOMPA survey
Avrajit Bandyopadhyay, Thirupathi Sivarani, Timothy C. Beers +3
We present a study on the detailed elemental abundances of newly identified bright very metal-poor stars with the detection of lithium, initially observed as part of the SDSS/MARVE…
Optical and NIR spectroscopy of cool CEMP stars to probe the nucleosynthesis in low mass AGB binary system
A. Susmitha, D. K. Ojha, T. Sivarani +4
We present the abundance analyses of 7 Carbon enhanced metal-poor (CEMP) stars to understand the origin of carbon in them. We used high-resolution optical spectra to derive abundan…
Abundance Analysis of New -Process-Enhanced Stars from the HESP-GOMPA Survey
Avrajit Bandyopadhyay, Thirupathi Sivarani, Timothy C. Beers
We present a study on the detailed chemical abundances of five new relatively bright -process-enhanced stars that were initially observed as part of the SDSS/MARVELS pre-survey.…
A high-resolution spectroscopic study of two new Na- and Al-rich field giants -- likely globular cluster escapees in the Galactic halo
Avrajit Bandyopadhyay, Sivarani Thirupathi, Timothy C. Beers +1
The stars SDSS J064655.6+411620.5 and SDSS J193712.01+502455.5 are relatively bright stars that were initially observed as part of the SDSS/MARVELS pre-survey. They were selected,…
