Open Clusters in the log Age vs. M_V plane
M. Bellazzini, S. Perina, S. Galleti +3
In the log Age vs. integrated absolute magnitude (M_V) plane, the open clusters of the Milky Way form a well-defined band parallel to theoretical sequences decribing the passive ev…
New Model Atmospheres: Testing the Solar Spectrum in the UV
L. H. Rodriguez-Merino, O. Cardona, E. Bertone +2
We present preliminary results on the calculation of synthetic spectra obtained with the stellar model atmospheres developed by Cardona, Crivellari, and Simonneau. These new models…
Population synthesis at short wavelengths and spectrophotometric diagnostic tools for galaxy evolution
A. Buzzoni, E. Bertone, M. Chavez +1
Taking advantage of recent important advances in the calculation of high-resolution spectral grids of stellar atmospheres at short wavelengths, and their implementation for populat…
UV excess and AGB evolution in elliptical-galaxy stellar populations
Rosa A. Gonzalez-Lopezlira, A. Buzzoni
The puzzling origin of the ``UV-upturn'' phenomenon, observed in some elliptical galaxies, has recently been settled by identifying hot HB stars as main contributors to galaxy ultr…
The extended structure of the remote cluster B514 in M31. Detection of extra-tidal stars
L. Federici, M. Bellazzini, S. Galleti +3
We present a study of the density profile of the remote M31 globular cluster B514, obtained from HST/ACS observations. Coupling the analysis of the distribution of the integrated l…
An updated survey of globular clusters in M31. II Newly discovered bright and remote clusters
S. Galleti, M. Bellazzini, L. Federici +2
We present the first results of a large spectroscopic survey of candidate globular clusters located in the extreme outskirts of the nearby M31 galaxy. We obtained low resolution sp…
