Distinct stellar-parameter dependencies of granulation and mesogranulation in red giants
Anohita Mallick, Jharnesh Verma, Shatanik Bhattacharya +1
Granulation and mesogranulation represent different spatial and temporal scales of convection, but are commonly assumed to follow the same stellar atmospheric scaling relations in…
A Quiet Host in an Active Planet-Forming Disk: Optical Spectroscopy of WISPIT 2
C. Swastik, M. Bestha, L. S. Sonith +11
WISPIT 2 is a young pre-main-sequence star hosting a multi-ringed transition disk and two directly imaged protoplanets, including the accreting WISPIT 2b, making it the closest kno…
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…
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…
Lithium abundances in giants as a function of stellar mass: An evidence for He-flash as the source of Li enhancement in low mass giants
Anohita Mallick, Raghubar Singh, Bacham E. Reddy
In this work, we studied the distribution of lithium abundances in giants as a function of stellar mass. We used a sample of 1240 giants common among Kepler photometric and LAMOST…
The Active Chromospheres of Lithium-Rich Red Giant Stars
Christopher Sneden, Melike Afsar, Zeynep Bozkurt +17
We have gathered near-infrared -band high resolution spectra of nearly 300 field red giant stars with known lithium abundances in order to survey their \species{He}{i} 1083…
Probing infrared excess connection with Li enhancement among red clump giants
Anohita Mallick, Bacham E. Reddy, C. Muthumariappan
We have performed a search among low mass red giants for finding evidence for merger scenario for triggering He-flash and subsequent Li enhancement. We chose a sample of red giants…
