The Pre--Main-Sequence of A-type stars

Marcella Marconi, Francesco Palla

Young A-type stars in the pre--main-sequence (PMS) evolutionary phase are particularly interesting objects since they cover the mass range (1.5-4 solar ma sses) which is most sensi…

RR Lyrae stars in Galactic globular clusters.III. Pulsational predictions for metal content Z=0.0001 to Z=0.006

Di Criscienzo M., M. Marconi, F. Caputo

The results of nonlinear, convective models of RR Lyrae pulsators with metal content Z=0.0001 to 0.006 are discussed and several predicted relations connecting pulsational (period…

Improvement of the CORS method for Cepheids radii determination based on Stromgren photometry

A. Ruoppo, V. Ripepi, M. Marconi +1

In this paper we present a modified version of the CORS method based on a new calibration of the Surface Brightness function in the Stromgren photometric system. The method has bee…

The distance to the LMC cluster Reticulum from the K-band Period-Luminosity-Metallicity relation of RR Lyrae stars

M. Dall'ora, J. Storm, G. Bono +12

We present new and accurate Near-Infrared J and Ks-band data of the Large Magellanic Cloud cluster Reticulum. Data were collected with SOFI available at NTT and covering an area of…

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…

Cepheid calibration of type Ia Supernovae and the Hubble constant

G. Altavilla, G. Fiorentino, M. Marconi +8

We investigate how a different calibration of the Cepheid Period-Luminosity (PL) relation taking into account the metallicity corrections, affects the absolute magnitude calibratio…
