    The IACOB project: XIV. New clues on the location of the TAMS in the massive star domain
    Context. Massive stars play a very important role in many astrophysical fields. Despite their scarcity with respect to less-massive counterparts, their...

    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...

    The influence of microlensing on the shape of the AGN Fe Kalpha line
    We study the influence of gravitational microlensing on the AGN Fe Kalpha line confirming that unexpected enhancements recently detected in the iron line of...

    The influence of the internal structuring of coronal loops on the properties of their damped transverse oscillations
    Context: The geometry and physical conditions in solar coronal loops are complicated and still not understood well. Recent high-resolution observations obtained...
