The ACS Survey of Galactic Globular Clusters. VII. Relative Ages
Antonio Marin-Franch, Antonio Aparicio, Giampaolo Piotto +13
The ACS Survey of Galactic Globular Clusters is a Hubble Space Telescope (HST) Treasury program designed to provide a new large, deep and homogeneous photometric database. Based on…
Stellar Population Models and Individual Element Abundances II: Stellar Spectra and Integrated Light Models
H. -c. Lee, G. Worthey, A. Dotter +7
The first paper in this series explored the effects of altering the chemical mixture of the stellar population on an element by element basis on stellar evolutionary tracks and iso…
Horizontal Branch Morphology and Mass Loss in Globular Clusters
Aaron Dotter
The connection between mass loss on the red giant branch (RGB) and horizontal branch (HB) morphology in globular clusters (GCs) has long been acknowledged but the mechanisms govern…
Globular Clusters in the Outer Galactic Halo: AM-1 and Palomar 14
Aaron Dotter, Ata Sarajedini, Soung-Chul Yang
AM-1, at ~120 kpc, and Pal 14, at ~70 kpc, are two of the most distant Galactic globular clusters known. We present Hubble Space Telescope WFPC2 photometry of AM-1 and Pal 14 that…
The Dartmouth Stellar Evolution Database
Aaron Dotter, Brian Chaboyer, Darko Jevremovic +3
The ever-expanding depth and quality of photometric and spectroscopic observations of stellar populations increase the need for theoretical models in regions of age-composition par…
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…
