Spectroscopic Survey of Faint Planetary-Nebula Nuclei. V. The EGB 6-Type Central Star of Abell 57
Howard E. Bond, Akshat S. Chaturvedi, Robin Ciardullo +3
During our spectroscopic survey of central stars of faint planetary nebulae (PNe), we found that the nucleus of Abell 57 exhibits strong nebular emission lines. Using synthetic nar…
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. III. The Double Subgiant Branch of NGC 1851
A. P. Milone, L. R. Bedin, G. Piotto +13
Photometry with HST's ACS reveals that the subgiant branch (SGB) of the globular cluster NGC 1851 splits into two well-defined branches. If the split is due only to an age effect,…
