  • The Active Chromospheres of Lithium-rich Red Giant Stars* 
    Sneden, Christopher; Afsar, Melike; Bozkurt, Zeynep; Adamow, Monika; Mallick, Anohita; Reddy, B. E; Janowiecki, Steven; Mahadevan, Suvrath; Bowler, Brendan P; Hawkins, Keith; Lind, Karin; Dupree, Andrea K; Ninan, Joe P; Nagarajan, Neel; Topcu, Gamze Bocek; Froning, Cynthia S; Bender, Chad F; Terrien, Ryan; Ramsey, Lawrence W; Mace, Gregory N (American Astronomical Society, 2022-11-20)
    We have gathered near-infrared zyJ-band high-resolution spectra of nearly 300 field red giant stars with known lithium abundances in order to survey their He I λ10830 absorption strengths. This transition is an indicator ...
