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…
The nature of ASASSN-24fw's occultation: modelling the event as dimming by optically thick rings around a sub-stellar companion
Sarang Shah, Jonathan P. Marshall, Carlos del Burgo +12
ASASSN-24fw is a main-sequence F-type star that experienced a rapid and long-lasting dimming event beginning in late 2024 and continuing until mid 2025. Its pre-dimming spectral en…
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…
Li-enrichment in red clump giants: Clues for past binary interaction or merger events
Raghubar Singh, Bacham E. Reddy, Anohita Mallick +1
To understand the underlying mechanisms for high lithium abundances among core He-burning or red clump (RC) giants, we analyzed a sample of 5227 RC giants of mass M 2~M$_{\o…
High Lithium Abundance Connection with the Chromospheric Helium in Red Giants: Spectroscopic and Asteroseismic analyses
Anohita Mallick, Christopher Sneden, Bacham E. Reddy +1
We present a study of correlations between high Li abundances and strong chromospheric He I 10830 Å absorption line strengths in Kepler field giant stars. Our sample includes 84 gi…
Study of a red clump giant, KIC~11087027, with high rotation and strong infrared excess -- Evidence of tidal interaction for high lithium abundance
Raghubar Singh, Anohita Mallick, Bacham E. Reddy +2
This paper presents results from Kepler photometric light curves and high-resolution spectroscopic study of a super Li-rich giant KIC11087027. Using the light curve analysis, we me…
