A new and Homogeneous metallicity scale for Galactic classical Cepheids. II. Abundance of iron and α elements

da Silva, R. Crestani, J. Bono, G.

Context. Classical Cepheids are the most popular distance indicators and tracers of young stellar populations. The key advantage is that they are bright and they can be easily identified in Local Group and Local Volume galaxies. Their evolutionary and pulsation properties depend on their chemical abundances. Aims: The main aim of this...

Milky Way archaeology using RR Lyrae and type II Cepheids

Prudil, Z. Hanke, M. Lemasle, B.

We present a chemo-dynamical study of the Orphan stellar stream using a catalog of RR Lyrae pulsating variable stars for which photometric, astrometric, and spectroscopic data are available. Employing low-resolution spectra from the Sloan Digital Sky Survey (SDSS), we determined line-of-sight velocities for individual exposures and derived the...
