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.

Abstract

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.
