Mining the GALAH data I: Study of five Super lithium-rich metal-poor giants
Antony Susmitha, Anohita Mallick, Bacham E. Reddy
The presence of a large amount of Li in giants is still a mystery. Most of the super Li-rich giants reported in recent studies are in the solar metallicity regime. Here, we study t…
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…
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…
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…
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…
