cds-question@unistra.frinfrared-astronomyspectroscopygiant-starsline-intensitieschemical-abundancesWe 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 HeI{lambda}10830 absorption strengths. This transition is an indicator of chromospheric activity and/or mass loss in red giants. The majority of stars in our sample reside in the red clump or red horizontal branch based on their V-J, M_V_ color-magnitude diagram, and Gaia Teff and log(g) values. Most of our target stars are Li-poor in the sense of having normally low Li abundances, defined here as log {epsilon}(Li)<1.25. Over 90% of these Li-poor stars have weak {lambda}10830 features. However, more than half of the 83 Li-rich stars (log{epsilon}(Li)>1.25) have strong {lambda}10830 absorptions. These large {lambda}10830 lines signal excess chromospheric activity in Li-rich stars; there is almost no indication of significant mass loss. The Li-rich giants may also have a higher binary fraction than Li-poor stars, based on their astrometric data. It appears likely that both residence on the horizontal branch and present or past binary interaction play roles in the significant Li-He connection established in this survey.2022ApJ...940...12Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/940/12CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/259 : The Tycho-2 Catalogue (Hog+ 2000)J/A+A/395/97 : RV and vsini of Ib supergiant stars (de Medeiros+, 2002)J/A+A/492/277 : Analysis of Collinder 69 stars with VOSA (Bayo+, 2008)J/AJ/135/209 : Rot. & radial velocities 761 HIP giants (Massarotti+, 2008)J/A+A/504/829 : Sp. survey of youngest field stars (Guillout+, 2009)J/AJ/140/1911 : Astrometric Grid Giant Star Survey.
