An empirical mass-loss law for Population II giants from the Spitzer-IRAC survey of Galactic globular clusters
L. Origlia, F. R. Ferraro, S. Fabbri +4
The main aim of the present work is to derive an empirical mass-loss (ML) law for Population II stars in first and second ascent red giant branches. We used the Spitzer InfraRed Ar…
The horizontal branch morphology of M31 Globular Clusters
M. Bellazzini, A. Buzzoni, C. Cacciari +4
We present the results of a first global analysis of the Horizontal Branch morphology of Globular Clusters in the nearby spiral M31, based on their Color Magnitude Diagrams.
The horizontal branch morphology of M31 globular clusters. Extreme second parameter effect in outer halo clusters
S. Perina, M. Bellazzini, A. Buzzoni +4
We use deep, high quality colour magnitude diagrams obtained with the Hubble Space Telescope to compute a simplified version of the Mironov index [SMI; B/(B+R)] to parametrize the…
The horizontal branch luminosity vs metallicity in M31 globular clusters
Luciana Federici, Carla Cacciari, Michele Bellazzini +3
Thanks to the outstanding capabilites of the HST, our current knowledge about the M31 globular clusters (GCs) is similar to our knowledge of the Milky Way GCs in the 1960s-1970s, w…
The Gaia spectrophotometric standard stars survey. I. Preliminary results
E. Pancino, G. Altavilla, S. Marinoni +23
We describe two ground based observing campaigns aimed at building a grid of approximately 200 spectrophotometric standard stars (SPSS), with an internal ~1% precision and tied to…
HST/ACS color-magnitude diagrams of candidate intermediate-age M 31 globular clusters. The role of blue horizontal branches
S. Perina, S. Galleti, F. Fusi Pecci +3
We present deep (V ~ 28.0) BV photometry obtained with the wide field channel of the Advanced Camera for Surveys on board HST for four M31 globular clusters that were identified as…
