Li Evolution and the Open Cluster NGC 6819: A Correlation Between Li Depletion and Spindown in Dwarfs More Massive Than the F-Dwarf Li-Dip
C. P. Deliyannis, B. J. Anthony-Twarog, D. B. Lee-Brown +1
Spectroscopy of 333 NGC 6819 stars and Gaia astrometry are used to map Li evolution from the giant branch tip to 0.5 mag below the Li dip. Isochrone comparison with [Fe/H] = -0.04,…
Li in Open Clusters: Cool Dwarfs in the Young, Subsolar Metallicity Cluster M35 (NGC 2168)
B. J. Anthony-Twarog, C. P. Deliyannis, D. Harmer +4
Hydra spectra of 85 G-K dwarfs in the young cluster, M35, near the Li 6708 Angstrom line region are analyzed. From velocities and Gaia astrometry, 78 are likely single-star members…
WIYN Open Cluster Study, LXXVI. Li Evolution Among Stars of Low/Intermediate Mass: The Metal-Deficient Open Cluster, NGC 2506
B. J. Anthony-Twarog, D. B. Lee-Brown, C. P. Deliyannis +1
HYDRA spectra of 287 stars in the field of NGC 2506 from the turnoff through the giant branch are analyzed. With previous data, 22 are identified as probable binaries; 90 more are…
The Ages of Passive Galaxies in a z=1.62 Protocluster
Donald B. Lee-Brown, Gregory H. Rudnick, Ivelina G. Momcheva +9
We present a study of the relation between galaxy stellar age and mass for 14 members of the protocluster IRC 0218, using multiband imaging and HST G102 and G141 grism spe…
