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…
Horizons: Nuclear Astrophysics in the 2020s and Beyond
H. Schatz, A. D. Becerril Reyes, A. Best +162
Nuclear Astrophysics is a field at the intersection of nuclear physics and astrophysics, which seeks to understand the nuclear engines of astronomical objects and the origin of the…
Globular Clusters UVIT Legacy Survey (GlobULeS) I. FUV-optical Color-Magnitude Diagrams for Eight Globular Clusters
Snehalata Sahu, Annapurni Subramaniam, Gaurav Singh +22
We present the first results of eight Globular Clusters (GCs) from the AstroSat/UVIT Legacy Survey program GlobULeS based on the observations carried out in two FUV filters (F148W…
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,…
Chemical composition of two bright extremely metal-poor stars from the SDSS MARVELS pre-survey
Avrajit Bandyopadhyay, Sivarani Thirupathi, Antony Susmitha +4
\sdsszeroeight\ (V = 11.4; [Fe/H] = 3.1) and \sdssonethree\ (V = 12.4; [Fe/H] = 3.2) were observed with the SDSS 2.5-m telescope as part of the SDSS-MARVELS spectroscopic pre…
Physics at a future Neutrino Factory and super-beam facility
The ISS Physics Working Group
The conclusions of the Physics Working Group of the international scoping study of a future Neutrino Factory and super-beam facility (the ISS) are presented. The ISS was carried by…
