    The orbital phases and secondary transits of Kepler-10b - A physical interpretation based on the Lava-ocean planet model.
    The Kepler mission has made an important observation, the first detection of photons from a terrestrial planet by observing its phase curve (Kepler-10b). This...

    The origin of the brightest stars in any Galaxy lies in stellar mergers
    Massive stars, those over ten times heavier than our Sun, are the conduits of most elements of the periodic table and drive the morphological and chemical...

    The phosphorus that came from the stars
    All chemical elements in the Universe (except for H and most of the He) have been made in stellar interiors. But among those elements, the ones that allowed to...

    The ratio of pattern speeds in double-barred galaxies.
    We have obtained two-dimensional velocity fields in the ionized gas of a set of eight double-barred galaxies, at high spatial and spectral resolution, using...

    The relic galaxy NGC 1277 lacks dark matter
    The standard cosmological model states that massive galaxies contain a large fraction of dark matter. Dark matter is a transparent substance that does not...

    The role of active galactic nucleus feedback on the evolution of dwarf galaxies from cosmological simulations: Supermassive black holes suppress star formation in low-mass galaxies
    Recent observational studies suggest that feedback from active galactic nuclei (AGNs)—the energetic centres powered by supermassive black holes—may play an...

    The role of the Sagittarius dwarf galaxy in the evolution of our Galaxy
    The European Space Agency's Gaia mission is revolutionising our understanding on how the Milky Way, the spiral galaxy we inhabit, has formed and evolved. Gaia...

    The rotation rates of massive stars: How slow are the slow ones?
    Rotation plays a key role in the life cycles of stars with masses above 8 Msun. Hence, accurate knowledge of the rotation rates of such massive stars is...

    The spectroscopic Hertzsprung-Russell diagram of Galactic massive stars.
    The distribution of stars in the Hertzsprung-Russell diagram narrates their evolutionary history and directly assesses their properties. Placing stars in this...
