    Chromospheric polarity reversals on sunspots. Are they consistent with weak line emission?
    Photospheric and chromospheric solar magnetograms sometimes show opposite polarity. This intriguing phenomenon is associated with the emergence of magnetic flux...

    Chromospheric reversals in the emergence of an ephemeral region
    Context: The behaviour of both ephemeral regions and moving magnetic features has been often described for the photospheric layer, but not for the chromosphere...

    Chromospheric Rotational Modulation in Solar-Like Stars - Part Two - Multicomponent Modelling and Rotational Period of Alpha-Centauri from CAII H Spectroscopic Variability
    The K1V late-type dwarf α Cen B has been monitored to search for spectroscopic variability in the Ca II H chromospheric line during its rotational period. The...

    Chronology of our Galaxy from Gaia colour-magnitude diagram fitting (ChronoGal): IV. The inner Milky Way stellar age distribution
    The Milky Way's inner region is dominated by a stellar bar and a boxy-peanut-shaped bulge. However, which stellar populations inhabit the inner Galaxy or how...

    Circularization and synchronization times in the main sequence of detached eclipsing binaries.I. Using the formalism by Tassoul.
    We have studied a sample of selected eclipsing binaries with eccentric orbits and accurate absolute dimensions in order to analyse the validity of available...
