Cepheids in external galaxies. I. The maser-host galaxy NGC 4258 and the metallicity dependence of P-L and P-W relations
G. Bono, F. Caputo, G. Fiorentino +2
We perform a detailed analysis of Cepheids in NGC 4258, Magellanic Clouds and Milky Way in order to verify the reliability of the theoretical scenario based on a large set of nonli…
On the newly discovered Canes Venatici II dSph galaxy
C. Greco, M. Dall'Ora, G. Clementini +11
We report on the detection of variable stars in the Canes Venatici II (CVn II) dwarf spheroidal galaxy, a new satellite of the Milky Way recently discovered by the Sloan Digital Sk…
Variable Stars in the Newly Discovered Milky Way Dwarf Spheroidal Satellite Canes Venatici I
Charles Kuehn, Karen Kinemuchi, Vincenzo Ripepi +11
We have identified 23 RR Lyrae stars and 3 possible Anomalous Cepheids among 84 candidate variables in the recently discovered Canes Venatici I dwarf spheroidal galaxy. The mean pe…
I Zw 18 revisited with HST/ACS and Cepheids: New Distance and Age
A. Aloisi, G. Clementini, M. Tosi +9
We present new V and I-band HST/ACS photometry of I Zw 18, the most metal-poor blue compact dwarf (BCD) galaxy in the nearby universe. It has been argued in the past that I Zw 18 i…
Classical Cepheid Pulsation Models. XI. Effects of convection and chemical composition on the Period-Luminosity and Period-Wesenheit relations
G. Fiorentino, M. Marconi, I. Musella +1
In spite of the relevance of Classical Cepheids as primary distance indicators, a general consensus on the dependence of the Period-Luminosity (PL) relation on the Cepheid chemical…
Very metal poor Classical Cepheids: variables in IZw18
G. Fiorentino, M. Marconi, G. Clementini +5
In the framework of an ongoing ACS@HST project (HST program #10586, PI: Aloisi) we have obtained deep multi-color imaging of the very metal-poor Blue Compact Dwarf galaxy IZw18. Th…
