Abundance of heavy r-process elements in CEMP-rs stars: The role of the i-process
A. M. Riyas, D. Karinkuzhi, S. Van Eck +6
Carbon-enhanced metal-poor (CEMP) stars are ancient stars enriched in carbon and heavy elements. Some of these stars exhibit enhanced s-process and/or r-process elements, hence are…
A chemodynamical study of -process-enhanced stars
Pallavi Saraf, Thirupathi Sivarani, Carlos Allende Prieto +2
The -process enrichment in the Galaxy still remains elusive with regard to its nucleosynthesis conditions and the astrophysical sites where it occurs. As part of ongoing efforts…
Asteroseismology of HD 23734, HD 68703, and HD 73345 using K2-TESS Space-based Photometry and High-resolution Spectroscopy
Santosh Joshi, Athul Dileep, Eugene Semenko +14
In this paper, we present a comprehensive study of three stars, HD 23734, HD 68703, and HD 73345, which were previously observed as chemically peculiar candidates within the Nainit…
On the Origin of Neutron-capture Elements in r-I and r-II Stars: A Differential-abundance Analysis
Pallavi Saraf, Thirupathi Sivarani, Timothy C. Beers +4
We present a strictly line-by-line differential analysis of a moderately -process-enhanced star (-I: HD~107752) with respect to a strongly -process-enhanced star (-II:…
