  • Publicación
    Unveiling shocks in planetary nebulae
    The propagation of a shock wave into a medium is expected to heat the material beyond the shock, producing noticeable effects in intensity line ratios such as...

    Unveiling the chemical fingerprint of phosphorus-rich stars. I. In the infrared region of APOGEE-2
    Context The origin of phosphorus, one of the essential elements for life on Earth, is currently unknown. Prevalent models of Galactic chemical evolution (GCE)...

    Unveiling the chemical fingerprint of phosphorus-rich stars: II. Heavy-element abundances from UVES/VLT spectra
    Context. The atmospheres of phosphorus-rich (P-rich) stars have been shown to contain between 10 and 100 times more P than our Sun. Given its crucial role as an...

    Variability of OB stars from TESS southern Sectors 1-13 and high-resolution IACOB and OWN spectroscopy
    Context. The lack of high-precision long-term continuous photometric data for large samples of stars has impeded the large-scale exploration of pulsational...

    Variable stars in Local Group Galaxies - I. Tracing the early chemical enrichment and radial gradients in the Sculptor dSph with RR Lyrae stars
    We identified and characterized the largest (536) RR Lyrae (RRL) sample in a Milky Way dSph satellite (Sculptor) based on optical photometry data collected over...

    Variable stars in local group galaxies - IV. RR Lyrae stars in the central regions of the low-density galaxy Crater II
    We present a search and analysis of variable stars in the recently discovered Crater II dwarf galaxy. Based on B, V, I data collected with the Isaac Newton...

    Variable stars in Local Group galaxies - V. The fast and early evolution of the low-mass Eridanus II dSph galaxy
    We present a detailed study of the variable star population of Eridanus II (Eri II), an ultra-faint dwarf galaxy that lies close to the Milky Way virial radius...
