BVI Photometry and the Red Giant Branch Luminosity Function of M15
Diane K. Feuillet, Nathaniel E. Q. Paust, Brian Chaboyer
We present new photometry containing 40,000 stars of the Galactic globular cluster M15 (NGC 7078) covering a arcminute area centered on the cluster with a magn…
The ACS Survey of Galactic Globular Clusters. XII. Photometric Binaries along the Main-Sequence
A. P. Milone, G. Piotto, L. R. Bedin +15
The fraction of binary stars is an important ingredient to interpret globular cluster dynamical evolution and their stellar population. We investigate the properties of main-sequen…
The ACS Survey of Galactic Globular Clusters. IX. Horizontal Branch Morphology and the Second Parameter Phenomenon
Aaron Dotter, Ata Sarajedini, Jay Anderson +11
The horizontal branch (HB) morphology of globular clusters (GCs) is most strongly influenced by metallicity. The second parameter phenomenon acknowledges that metallicity alone is…
