Detailed Composition of Starts in Dwarf Spheroidal Galaxies
Matthew Shetrone
A refereed review paper which covers high resolution abundances in dSph galaxies.
S986 in M67: A Totally-Eclipsing Binary at the Cluster Turnoff
Eric L. Sandquist, Matthew D. Shetrone
We have discovered that the star S986 in the old open cluster M67 has detectable total eclipses of depth 0.08 mag for the primary eclipse and 0.011 mag for the secondary eclipse (i…
Possible Post-AGB Stars
G. Wallerstein, G. Gonzalez, M. D. Shetrone
Radial velocities were measured for 5 potential post-AGB stars, two in the globular cluster NGC 1851 and three in the dSph galaxy Ursa Minor. All five potential PAGB stars were fou…
A Comparison of Copper Abundances in Globular Cluster and Halo Field Giant Stars
Jennifer Simmerer, Christopher Sneden, Inese I. Ivans +3
We derive [Cu/Fe] for 117 giant stars in ten globular clusters (M3, M4, M5, M10, M13, M15, M71, NGC 7006, NCG 288, and NGC 362) and find that globular cluster Cu abundances appear…
Time-Series Photometry of M67: W UMa Systems, Blue Stragglers, and Related Systems
Eric L. Sandquist, Matthew D. Shetrone
We present an analysis of over 2200 V images taken on 14 nights at the Mt. Laguna 1 m telescope of the open cluster M67. Our observations overlap but extend beyond the field analyz…
