Detailed chemical composition of classical Cepheids in the LMC cluster NGC 1866 and in the field of the SMC
B. Lemasle, M. A. T. Groenewegen, E. K. Grebel +11
Context: Cepheids are excellent tracers of young stellar populations. They play a crucial role in astrophysics as standard candles. The chemistry of classical Cepheids in the Milky…
On the fine structure of the Cepheid metallicity gradient in the Galactic thin disk
K. Genovali, B. Lemasle, G. Bono +15
We present homogeneous and accurate iron abundances for 42 Galactic Cepheids based on high-spectral resolution (R~38,000) high signal-to-noise ratio (SNR>100) optical spectra colle…
Galactic abundance gradients from Cepheids: alpha and heavy elements in the outer disk
B. Lemasle, P. Francois, K. Genovali +11
Context: Galactic abundance gradients set strong constraints to chemo-dynamical evolutionary models of the Milky Way. Given the PL relations that provide accurate distances and the…
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…
