    The universal variability of the stellar initial mass function probed by the TIMER survey
    The universality of the stellar initial mass function (IMF) is one of the most widespread assumptions in modern Astronomy and yet, it might be flawed. While...

    The unusual vertical mass distribution of NGC 4013 seen though the Spitzer Survey of Stellar Structure in Galaxies (S4G).
    NGC 4013 is a nearby Sb edge-on galaxy known for its “prodigious” HI warp and its “giant” tidal stream. Previous work on this unusual object shows that it...

    Three supernova shells around a young star cluster in M33
    Using a specialized technique sensitive to the presence of expanding ionized gas, we have detected a set of three concentric expanding shells in an H ii region...

    Tidally trapped pulsations in a close binary star system
    It has long been suspected that tidal forces in close binary stars could modify the orientation of the pulsation axis of the constituent stars. Such stars have...

    TrES-2
    In August 2006 a new planetary transit was discovered from data from the TrES network. The discovery was confirmed using radial velocity curves obtained with...

    Type-II surface brightness profiles in edge-on galaxies produced by flares
    Previous numerical studies had apparently ruled out the possibility that flares in galaxy discs could give rise to the apparent breaks in their luminosity...

    Unnoticed magnetic field oscillations in the very quiet Sun revealed by Sunrise/IMaX.
    As we enhance the spatial resolution and sensitivity of spectro-polarimetric measurements, it becomes increasingly evident that highly dynamic magnetic fields...

    Unravelling coronal bright points
    When the Sun is observed in X-ray or extreme ultraviolet wavelengths, hundreds of bright and compact structures with a rounded shape and sizes similar to that...

    Unveiling the companion of Aquila X-1 40 years after its discovery
    Low mass X-ray binaries consist of two components: a compact object (either a neutron star or a stellar-mass black hole) and a star with a mass similar or lower...
