Descripción
We present the Oscillating Stars with wIneRed near-Infrared Spectroscopy
(OSIRIS) project, aimed at deriving accurate chemical abundances of
primary distance indicators covering a wide age range from young
Classical Cepheids to intermediate-age Anomalous Cepheids and Miras, old
RR Lyrae stars, and Type-II Cepheids. High-resolution near-infrared
spectra will be collected with WINERED, a Japanese instrument with the
highest available throughput in the range 0.9-1.35 μm. We summarize
here the characteristics of the instrument, the data acquisition and
reduction, and preliminary results.
