Galactic abundance gradients from Cepheids : On the iron abundance gradient around 10-12 kpc
B. Lemasle, P. Francois, A. Piersimoni +5
Context: Classical Cepheids can be adopted to trace the chemical evolution of the Galactic disk since their distances can be estimated with very high accuracy. Aims: Homogeneous ir…
Relative distances of Omega Centauri and 47 Tucanae
G. Bono, P. B. Stetson, N. Sanna +18
We present precise optical and near-infrared ground-based photometry of two Globular Clusters (GCs): Omega Cen and 47 Tuc. These photometric catalogs are unbiased in the Red Giant…
MAD@VLT: Deep into the Madding Crowd of Omega Centauri
G. Bono, A. Calamida, C. E. Corsi +18
We present deep and accurate Near-Infrared (NIR) photometry of the Galactic Globular Cluster (GC) Omega Cen. Data were collected using the Multi-Conjugate Adaptive Optics Demonstra…
Metallicity estimates of Galactic Cepheids based on Walraven photometry
S. Pedicelli, J. Lub, J. W. Pel +13
We present new empirical and theoretical calibrations of two photometric metallicity indices based on Walraven photometry. The empirical calibration relies on a sample of 48 Cephei…
The infrared JHK light curves of RR Lyr
A. Sollima, C. Cacciari, A. A. Arkharov +4
We present infrared JHK time series photometry of the variable star RR Lyr, that allow us to construct the first complete and accurate infrared light curves for this star. The deri…
Cepheids as tracers of the metallicity gradient across the Galactic disk
B. Lemasle, A. Piersimoni, S. Pedicelli +4
We present iron abundance measurements, based on high resolution spectroscopy, and accurate distance determinations, based on near infrared photometry, for 34 Galactic Cepheids. Th…
