On the metallicity distribution of classical Cepheids in the Galactic inner disk
K. Genovali, B. Lemasle, G. Bono +10
We present homogeneous and accurate iron abundances for almost four dozen (47) of Galactic Cepheids using high-spectral resolution (R40,000) high signal-to-noise ratio (S/N $…
On the binarity of the classical Cepheid X Sgr from interferometric observations
G. Li Causi, S. Antoniucci, G. Bono +4
Optical-infrared interferometry can provide direct geometrical measurements of the radii of Cepheids and/or reveal unknown binary companions of these stars. Such information is of…
CORS Baade-Wesselink method in the Walraven photometric system: the Period-Radius and the Period-Luminosity relation of Classical Cepheids
R. Molinaro, V. Ripepi, M. Marconi +4
We present a new derivation of the CORS Baade-Wesselink method in the Walraven photometric system. We solved the complete Baade-Wesselink equation by calibrating the surface bright…
New Baade-Wesselink distances and radii for four metal-rich Galactic Cepheids
S. Pedicelli, B. Lemasle, M. Groenewegen +10
We provided accurate estimates of distances, radii and iron abundances for four metal-rich Cepheids, namely V340 Ara, UZ Sct, AV Sgr and VY Sgr. The main aim of this investigation…
The Dependency of the Cepheid Period-Luminosity Relation on Chemical Composition
M. Romaniello, F. Primas, M. Mottini +6
The dependency of the Cepheid Period-Luminosity Relation on chemical composition at different wavelengths is assessed via direct detailed abundance analysis of Galactic and Magella…
