Evolutionary and pulsation properties of Type II Cepheids
G. Bono, V. F. Braga, G. Fiorentino +7
We discuss the observed pulsation properties of Type II Cepheids (TIICs) in the Galaxy and Magellanic Clouds. The period (P) distributions, luminosity amplitudes and population rat…
Self-enrichment in Globular Clusters: the extreme He-rich population of NGC 2808
Marcella Di Criscienzo, Paolo Ventura, Francesca D'Antona +2
Almost several decades after the discovery of the first multiple populations in galactic globular clusters (GC) the debate on their formation is still extremely current and NGC2808…
The Star Formation Main Sequence in the Hubble Space Telescope Frontier Fields
Paola Santini, Adriano Fontana, Marco Castellano +13
We investigate the relation between the star formation rate (SFR) and the stellar mass (M), i.e. the Main Sequence (MS) relation of star-forming galaxies, at 1.3<=z<6 in the first…
Probing O-enrichment in C-rich dust planetary nebulae
D. A. Garcia-Hernandez, P. Ventura, G. Delgado-Inglada +3
The abundance of O in planetary nebulae (PNe) has been historically used as a metallicity indicator of the interstellar medium (ISM) where they originated; e.g., it has been widely…
Rapidly rotating second-generation progenitors for the blue hook stars of ω Cen
Marco Tailo, Francesca D'Antona, Enrico Vesperini +9
Horizontal Branch stars belong to an advanced stage in the evolution of the oldest stellar galactic population, occurring either as field halo stars or grouped in globular clusters…
