Blue Hook Stars in Globular Clusters
A. Dieball, C. Knigge, T. J. Maccarone +4
Blue hook (BHk) stars are a rare class of horizontal branch stars that so far have been found in only very few Galactic globular clusters (GCs). The dominant mechanism for producin…
Parallax and Distance Estimates for Twelve Cataclysmic Variable Stars
J. R. Thorstensen, S. Lepine, M. Shara
We report parallax and distance estimates for twelve more cataclysmic binaries and related objects observed with the 2.4m Hiltner telescope at MDM Observatory. The final parallax a…
Stellar Exotica in 47 Tucanae
Christian Knigge, Andrea Dieball, Jesus Maiz Apellaniz +3
We present far-UV spectroscopy obtained with HST for 48 blue objects in the core of 47 Tuc. Based on their position in a FUV-optical colour-magnitude diagram, these were expected t…
Deep ACS Imaging in the Globular Cluster NGC6397: Dynamical Models
Jarrod R. Hurley, Michael M. Shara, Harvey B. Richer +8
We present N-body models to complement deep imaging of the metal-poor core-collapsed cluster NGC6397 obtained with the Hubble Space Telescope. All simulations include stellar and b…
The core binary fractions of star clusters from realistic simulations
Jarrod R. Hurley, Sverre J. Aarseth, Michael M. Shara
We investigate the evolution of binary fractions in star clusters using N-body models of up to 100000 stars. Primordial binary frequencies in these models range from 5% to 50%. Sim…
