    Observational constraints on the optical and near-infrared emission from the neutron star-black hole binary merger candidate S190814bv
    Context. Gravitational wave (GW) astronomy has rapidly reached maturity, becoming a fundamental observing window for modern astrophysics. The coalescences of a...

    Observational hints of radial migration in disc galaxies from CALIFA
    Context. According to numerical simulations, stars are not always kept at their birth galactocentric distances but they have a tendency to migrate. The...

    Observational results for eight long-period comets observed far from the Sun
    Context. With this work we start a systematic analysis of the distant activity of several long-period comets in order to investigate the evolution of activity...

    Observational studies of Cepheid amplitudes. I. Period-amplitude relationships for Galactic Cepheids and interrelation of amplitudes
    Context: The dependence of amplitude on the pulsation period differs from other Cepheid-related relationships. Aims: We attempt to revise the period-amplitude...

    Observational studies of Cepheid amplitudes. II. Metallicity dependence of pulsation amplitudes
    Context. Physical and phenomenological properties (radius, luminosity, shape of the light curve, etc.) of Cepheids strongly depend on the pulsation period, with...

    Observations of Ellerman bomb emission features in He i D3 and He i 10 830 Å
    Context. Ellerman bombs (EBs) are short-lived emission features, characterised by extended wing emission in hydrogen Balmer lines. Until now, no distinct...
