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.

    RAD@home Citizen Scientists Uncover Emerging Jet-Galaxy Interactions
    The RAD12 object's recent investigation (Hota et al. 2022), via the RAD@home Astronomy Collaboratory, has provided a streamlined and focused perspective on the complex subject of jet-galaxy interactions, which has always posed a significant challenge for observational confirmation. This emerging field holds increasing significance, providing a

    A Disc Wind Where You Least Expect It: The Outflow in the Short-period X-ray Binary UW CrB
    Studying outflows of low mass X-ray binaries (LMXBs) is important for understanding the physics of accretion, the evolution of compact binaries, and dynamics of the local interstellar medium. One significant source of these outflows is the accretion disc wind, which can blow away vast amounts of material from the disc before it can be accreted on

    Constraining the core-rotation rate along the red-giant evolution
    The evolution of the core rotation rate of red giant stars is a key parameter in understanding the stellar behavior in the late phases of stellar evolution. Thanks to the mixed-dipole modes, we can constrain the core rotation and internal rotational gradient as a star advances through the red-giant phase. This master thesis presents a pipeline
