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…
First Stars XI. Chemical composition of the extremely metal-poor dwarfs in the binary CS 22876--032
J. I. González Hernández, P. Bonifacio, H. -G. Ludwig +15
We have used high-resolution, high-S/N ratio spectra from the UVES spectrograph at the ESO VLT telescope. Long-term radial-velocity measurements and broad-band photometry allow us…
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…
Detailed chemical composition of Galactic Cepheids. A determination of the Galactic abundance gradient in the 8-12 kpc region
B. Lemasle, P. Francois, G. Bono +3
The recent introduction of high resolution/large spectral range spectrographs provided the opportunity to investigate in detail the chemical composition of classical Cepheids. This…
