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…
Detection of new variable stars in the SMC cluster NGC 121
G. Fiorentino, R. Contreras, G. Clementini +5
New candidate variable stars have been identified in the Small Magellanic Cloud cluster NGC121, by applying both the image subtraction technique (ISIS, Alard 2000) and the Welch &…
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…
Cepheid pulsation models at varying metallicity and DY/DZ
M. Marconi, I. Musella, G. Fiorentino
In this paper we present an extended set of nonlinear convective pulsation models at varying the metallicity and DY/DZ ratio. The predicted instability strip and bolometric light c…
Pulsation and evolutionary masses of classical Cepheids. I. Milky Way variables
F. Caputo, G. Bono, G. Fiorentino +2
We investigate a selected sample of Galactic classical Cepheids with available distance and reddening estimates in the framework of the theoretical scenario provided by pulsation m…
Updated pulsation models for anomalous Cepheids
M. Marconi, G. Fiorentino, F. Caputo
A theoretical investigation of the pulsation behavior of so-named ``anomalous'' Cepheids is presented. The study is based on nonlinear convective pulsation models with =0.0001 a…
