Evolved Stars in the Core of the Massive Globular Cluster NGC 2419
Eric L. Sandquist, Jordan M. Hess
We present an analysis of optical and ultraviolet Hubble Space Telescope photometry for evolved stars in the core of the distant massive globular cluster NGC 2419. We characterize…
Photometry of the Globular Cluster NGC 5466: Red Giants and Blue Stragglers
Nassissie Fekadu, Eric L. Sandquist, Michael Bolte
We present wide-field BVI photometry for about 11,500 stars in the low-metallicity cluster NGC 5466. We have detected the red giant branch bump for the first time, although it is a…
Theoretical orbital period distributions of cataclysmic variables above the period gap: effects of circumbinary disks
B. Willems, R. Taam, U. Kolb +2
The population of non magnetic cataclysmic variables evolving under the influence of a circumbinary disk is investigated for systems above the upper edge of the period gap at orbit…
Blue Stragglers in Low-Luminosity Star Clusters
Eric L. Sandquist
We examine the blue straggler populations of 13 low-luminosity (M_V_t >~ -6) globular clusters and 2 old open clusters. These clusters test blue straggler formation in environments…
Angular momentum losses and the orbital period distribution of cataclysmic variables below the period gap: effects of circumbinary disks
B. Willems, U. Kolb, E. L. Sandquist +2
The population synthesis of cataclysmic variables below the period is investigated. A grid of detailed binary evolutionary sequences has been calculated and included in the simulat…
Time-Series Ensemble Photometry and the Search for Variable Stars in the Open Cluster M11
Jonathan R. Hargis, Eric L. Sandquist, David H. Bradstreet
This work presents the first large-scale photometric variability survey of the intermediate age (~200 Myr) open cluster M11. Thirteen nights of data over two observing seasons were…
