Petersen diagram for RRd stars in the Magellanic Clouds
B. L. Popielski, W. A. Dziembowski, S. Cassisi
RRd stars from the Magellanic Clouds form a well-defined band in the Petersen diagram. We explain this observed band with our evolutionary and pulsation calculations with assumed m…
Antlia: an outskirt Local Group Galaxy
Marco Castellani, Giuseppe Bono, Santi Cassisi +2
Deep (I,V-I) and (I,B-I) color-magnitude diagrams (CMDs) of the Antlia dwarf galaxy, based on Science Verification (SV) data collected with the FORS I camera on the ESO Very Large…
The anomalous Galactic globular cluster NGC 2808
L. R. Bedin, G. Piotto, M. Zoccali +4
We present UBVI photometry for about 60,000 stars in a region of 44'x33' centered on the Galactic globular cluster (GGC) NGC 2808. The central region has been mapped with the HST W…
The role of NCO reaction chain on the He ignition in degenerate stellar structures
L. Piersanti, S. Cassisi, A. Tornambe'
The role played by NCO reaction in the onset of the He flash in the He core of a RGB star and in low mass CO WDs accreting H/He rich matter is investigated.
