The Effect of Metallicity on the Cepheid Period-Luminosity Relation
Martino Romaniello, Francesca Primas, Marta Mottini +1
We present preliminary results of an observational campaign devoted at establishing the influence of chemical composition on the Cepheid Period-Luminosity relation. The data are in…
Determining the Metallicity of Cepheid Stars in the SMC, LMC and the Galaxy
M. Mottini, F. Primas, M. Romaniello +1
The Cepheid Period-Luminosity relation is unquestionably one of the most powerful tools at our disposal for determining the extragalactic distance scale. While significant progress…
The Extremely Metal-Poor, Neutron-Capture-Rich Star CS 22892-052: A Comprehensive Abundance Analysis
C. Sneden, J. J. Cowan, J. E. Lawler +9
High-resolution spectra obtained with three ground-based facilities and the Hubble Space Telescope (HST) have been combined to produce a new abundance analysis of CS 22892-052, an…
