Unveiling the nature of barium stars. I. Asteroseismic masses and the evolutionary link between Ba dwarfs and giants
Lupamudra Sarmah, Yerra Bharat Kumar, Simon W. Campbell +2
Barium star systems are excellent sites for studying AGB nucleosynthesis, binary evolution, and mass transfer processes. However, an accurate estimation of their fundamental stella…
Asteroseismology of Carbon-Deficient Red Giants: Merger Products of Hierarchical Triple Systems?
Sunayana Maben, Simon W. Campbell, Timothy R. Bedding +4
Carbon-deficient giants (CDGs) are a rare and chemically peculiar class of stars whose origins remain under active investigation. We present an asteroseismic analysis of the entire…
Asteroseismology sheds light on the origin of carbon-deficient red giants: likely merger products and linked to the Li-rich giants
Sunayana Maben, Simon W. Campbell, Yerra Bharat Kumar +2
Carbon-deficient red giants (CDGs) are a peculiar class of stars that have eluded explanation for decades. We aim to better characterise CDGs by using asteroseismology (Kepler, TES…
A large sample of newly-identified carbon-deficient red giants from APOGEE
Sunayana Maben, Yerra Bharat Kumar, Bacham E. Reddy +2
Based on the APOGEE survey we conducted a search for carbon-deficient red giants (CDGs). We found 103 new CDGs, increasing the number in the literature by more than a factor of 3.…
Discovery of ubiquitous lithium production in low-mass stars
Yerra Bharat Kumar, Bacham E. Reddy, Simon W. Campbell +3
The vast majority of stars with mass similar to the Sun are expected to only destroy lithium over the course of their lives, via low-temperature nuclear burning. This has now been…
