    Resolving the unresolved: Discovery and dynamical masses of the brown dwarf binary DE1756−45
    We present a method of resolving the geometric structure in unresolved CCD images of the two-component stellar objects with relative separations below the full...

    Resonant absorption: Transformation of compressive motions into vortical motions
    This paper investigates the changes in spatial properties when magnetohydrodynamic (MHD) waves undergo resonant damping in the Alfvén continuum. The analysis is...

    Resonantly damped fast MHD kink modes in longitudinally stratified tubes with thick non-uniform transitional layers
    Resonantly damped fast kink quasi-modes are computed in fully resistive magnetohydrodynamics (MHD) for two-dimensional equilibrium models. The equilibrium model...

    Response functions for the inversion of data from unresolved solar magnetic elements.
    By adopting the thin flux tube model as representative of spatially unresolved magnetic elements in the photosphere of the Sun, we identify an adequate set of...

    Retrieval of solar magnetic fields from high-spatial resolution filtergraph data: the Imaging Magnetograph eXperiment (IMaX)
    Context. The design of modern instruments does not only imply thorough studies of instrumental effects but also a good understanding of the scientific analysis...

    Retrieval of the physical parameters of galaxies from WEAVE-StePS-like data using machine learning
    Context. The William Herschel Telescope Enhanced Area Velocity Explorer (WEAVE) is a new, massively multiplexing spectrograph that allows us to collect about...

    Retrieving day- and nightside atmospheric properties of the ultra-hot Jupiter TOI-2109b: Detection of Fe and CO emission lines and evidence for inefficient heat transport
    The ultra-hot Jupiter (UHJ) TOI-2109b marks the lower edge of the equilibrium temperature gap between 3500 and 4500 K, an unexplored thermal regime that...

    Retrieving the transmission spectrum of HD 209458b using CHOCOLATE: a new chromatic Doppler tomography technique
    Multiband photometric transit observations or low-resolution spectroscopy (spectro-photometry) are normally used to retrieve the broadband transmission spectra...

    Returning magnetic flux in sunspot penumbrae
    Aims: We study the presence of reversed polarity magnetic flux in sunspot penumbra. Methods: We applied a new regularized method to deconvolve...
