Discovery of Carbon/Oxygen depleted Blue Straggler Stars in 47 Tucanae: the chemical signature of a mass-transfer formation process
F. R. Ferraro, E. Sabbi, R. Gratton +10
We use high-resolution spectra obtained with the ESO Very Large Telescope to measure surface abundance patterns of 43 Blue Stragglers stars (BSS) in 47 Tuc. We discovered that a su…
The Electron Temperature Gradient in the Galactic Disk
C. Quireza, R. T. Rood, T. M. Bania +2
We derive the electron temperature gradient in the Galactic disk using a sample of HII regions that spans Galactocentric distances 0--17 kpc. The electron temperature was calculate…
Radio Recombination Lines in Galactic HII Regions
Cintia Quireza, Robert T. Rood, Dana S. Balser +1
We report radio recombination line (RRL) and continuum observations of a sample of 106 Galactic HII regions made with the NRAO 140 Foot radio telescope in Green Bank, WV. We believ…
The dynamical state and blue straggler population of the globular cluster NGC 6266 (M62)
G. Beccari, F. R. Ferraro, A. Possenti +3
We have used a proper combination of multiband high-resolution {\it HST-WFPC2} and wide-field ground based observations to image the galactic globular cluster NGC 6266 (M62). The e…
