Central DM density cuspiness in LSB's: a stellar kinematics approach
A. Pizzella, E. M. Corsini, F. Bertola +4
We present preliminary results from spectroscopic observations of a sample of 11 low surface brightness galaxies (LSB). We measured the stellar and gaseous kinematics along their m…
The sigma_c-V_c correlation in high and low surface brightness galaxies
A. Pizzella, E. Dalla Bonta', E. M. Corsini +2
We investigate the relation between the central velocity dispersion, sigma_0, and the circular velocity, V_c, in galaxies. In addition to previously available data, we consider an…
Supernova Statistics
Enrico Cappellaro, Roberto Barbon, Massimo Turatto
The statistics of SN discoveries is used to reveal selection biases of past and current SN searches and to gain insight on the progenitor scenarios for the different SN types. We a…
Variable stars as tracers of stellar populations in Local Group galaxies: Leo I and NGC 6822
L. Baldacci, F. Matonti, L. Rizzi +5
Results are presented of a study of the variable star populations in the dwarf spheroidal galaxy Leo I and in the dwarf irregular galaxy NGC 6822, based on time series photometry o…
The Red Giant Branch Bump
M. Riello, G. Piotto, A. Recio-Blanco +2
We present a comparison between theoretical models and the observed magnitude difference between the horizontal branch and the red giant branch bump for a sample of 53 clusters. We…
Rotation of Hot Horizontal Branch Stars in Galactic Globular Clusters
A. Recio-Blanco, G. Piotto, A. Aparicio +1
We present high resolution UVES+VLT spectroscopic observations of 61 stars in the extended blue horizontal branches of the Galactic globular clusters NGC 1904 (M79), NGC 2808, NGC…
