Research Output from Lick Observatory for 1965-2019
Graeme H. Smith, Matthew Shetrone
The productivity of Lick Observatory (LO) is reviewed over the years from 1965 to 2019, a 55 yr period which commences with the Shane 3 m telescope being the second-largest astrono…
Carbon Abundance Inhomogeneities and Deep Mixing Rates in Galactic Globular Clusters
Jeffrey M. Gerber, Michael M. Briley, Graeme H. Smith
Among stars in Galactic globular clusters the carbon abundance tends to decrease with increasing luminosity on the upper red giant branch, particularly within the lowest metallicit…
A Catalog of Stellar Unified Properties (CATSUP) for 951 FGK-Stars Within 30 pc
Natalie R. Hinkel, Eric E. Mamajek, Margaret C. Turnbull +6
Almost every star in our Galaxy is likely to harbor a terrestrial planet, but accurate measurements of an exoplanet's mass and radius demands accurate knowledge of the properties o…
Carbon Stars in the Satellites and Halo of M31
Katherine Hamren, Rachael L. Beaton, Puragra GuhaThakurta +7
We spectroscopically identify a sample of carbon stars in the satellites and halo of M31 using moderate-resolution optical spectroscopy from the Spectroscopic and Photometric Lands…
A Spectroscopic and Photometric Exploration of the C/M Ratio in the Disk of M31
Katherine M. Hamren, Constance M. Rockosi, Puragra Guhathakurta +12
We explore the ratio (C/M) of carbon-rich to oxygen-rich thermally pulsing asymptotic giant branch(TP-AGB) stars in the disk of M31 using a combination of moderate-resolution optic…
The 10830 Angstrom Helium Line Among Evolved Stars in the Globular Cluster M4
Jay Strader, A. K. Dupree, Graeme H. Smith
Helium is a pivotal element in understanding multiple main sequences and extended horizontal branches observed in some globular clusters. Here we present a spectroscopic study of h…
