    On the nature of VX Sagitarii: Is it the first galactic super-AGB star found?
    Stars with initial masses above ~10 M ⊙ have an internal evolution completely different from those in the range between 4 and ~10 M ⊙. The former are able to ignite all the elements up to Fe in their cores without degeneration (becoming into red supergiants; RSGs). The latter are not, and they become into red giants first, and later into asymptotic

    Stellar atmospheric parameters of CARMENES GTO M dwarfs with spectral synthesis and SteParSyn
    We aim to review the spectral synthesis technique to derive the stellar atmospheric parameters (T eff, log g, and [Fe/H]) of 348 M dwarfs in light of the optical and near-infrared spectra obtained with CARMENES, the high-resolution, double-channel spectrograph installed at the 3.5 m telescope at the Calar Alto observatory (Spain). The analysis

    Surface rotation and magnetic activity for 55,000+ Kepler solar-type stars
    Dark magnetic spots co-rotating with the stellar surface lead to quasi-periodic brightness variations, which enclose relevant information on stellar rotation and magnetic activity properties. In this work, we analyzed the Kepler long-cadence data of 159,710 main-sequence and subgiant FGKM stars. Rotation-period candidates are obtained by combining

    The Lines are Not Fine: Measuring Vanadium Abundances in M dwarfs from Hyperfine-Split Lines
    Cool star atmospheres present challenges to chemical abundance studies. To date, only a handful of elements have been quantified for a handful of M dwarfs. In high-resolution spectra from the CARMENES survey, we identify a series of dramatically hyperfine-split vanadium features between 800 and 910 nm, which have strong and clean profiles

    The 99942 Apophis observational campaign at the Canary Islands observatories during its 2021 close approach: preliminary results
    Potentially hazardous asteroid (PHA) 99942 Apophis, with a diameter 380-393 m (Licandro et al. 2016), came to its 2021 close approach on March 6, 2021, at 01:06 UT. It approached at 0.1126 au from Earth, providing an excellent opportunity to obtain good data to do a detailed study of its physical properties. The Solar System Group of the Instituto
