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…
The influence of chemical composition on the properties of Cepheid stars. II-The iron content
M. Romaniello, F. Primas, M. Mottini +6
The Cepheid period-luminosity (PL) relation is unquestionably one of the most powerful tools at our disposal for determining the extragalactic distance scale. While significant pro…
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…
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…
