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…

Spectroscopic Abundances in the Open Cluster, NGC 6819

Donald B. Lee-Brown, Barbara J. Anthony-Twarog, Constantine P. Deliyannis +2

High-dispersion spectra of 333 stars in the open cluster NGC 6819, obtained using the HYDRA spectrograph on the WIYN 3.5m telescope, have been analyzed to determine the abundances…
