Stars of the Draco Dwarf Spheroidal Galaxy Beyond its Measured Tidal Boundary
Slawomir Piatek, Carlton Pryor, Taft E. Armandroff +1
We report R- and V-band photometry derived from CCD imaging for objects in nine fields in and around the Draco dwarf spheroidal galaxy. The most distant fields are about 1.3 degree…
The Age of the Inner Halo Globular Cluster NGC 6652
Brian Chaboyer, Ata Sarajedini, Taft E. Armandroff
HST (V,I) photometry has been obtained for the inner halo globular cluster NGC 6652. The photometry reaches approximately 4 mag below the turn-off and includes a well populated hor…
Neutron-Capture Elements in the Early Galaxy: Insights from a Large Sample of Metal-Poor Giants
Debra L. Burris, Catherine A. Pilachowski, Taft E. Armandroff +3
New abundances for neutron-capture (n-capture) elements in a large sample of metal-poor giants from the Bond survey are presented. The spectra were acquired with the KPNO 4-m echel…
