    The IACOB project. X. Large-scale quantitative spectroscopic analysis of Galactic luminous blue stars
    Context. Blue supergiants (BSGs) are key objects for understanding the evolution of massive stars, which play a crucial role in the evolution of galaxies...

    The IACOB project. XI. No increase in mass-loss rates over the bistability region
    The properties of blue supergiants are key for constraining the end of the main sequence (MS) of massive stars. Whether the observed drop in the relative number...

    The IACOB project: XII. New grid of northern standards for the spectral classification of B-type stars
    Context. With the advent of large spectroscopic surveys, automated stellar parameter determination has become commonplace. Nevertheless, spectral classification...

    The impact of surface dynamo magnetic fields on the solar iron abundance
    Most chemical abundance determinations ignore that the solar photosphere is significantly magnetized by the ubiquitous presence of a small-scale magnetic field...

    The implications of the surprising existence of a large, massive CO disk in a distant protocluster
    It is not yet known if the properties of molecular gas in distant protocluster galaxies are significantly affected by their environment as galaxies are in local...

    The imprint of cosmological hydrogen recombination lines on the power spectrum of the CMB
    We explore the imprint of the cosmological hydrogen recombination lines on the power spectrum of the cosmic microwave background (CMB). In particular, we focus...

    The inflated, eccentric warm Jupiter TOI-4914 b orbiting a metal-poor star, and the hot Jupiters TOI-2714 b and TOI-2981 b
    Recent observations of giant planets have revealed unexpected bulk densities. Hot Jupiters, in particular, appear larger than expected for their masses compared...

    The influence of longitudinal density variation in coronal loops on the eigenfunctions of kink-oscillation overtones
    Context: As coronal loops are spatially at least partially resolved in the longitudinal direction, attempts have been made to use the longitudinal profiles of...

    The influence of microlensing on spectral line shapes generated by a relativistic accretion disc
    We study the influence of gravitational microlensing on the spectral line profiles originating from a relativistic accretion disc. Using the Chen & Halpern...
