    Unresolved Rossby and gravity modes in 214 A and F stars showing rotational modulation
    Here, we report an ensemble study of 214 A- and F-type stars observed by Kepler, exhibiting the so-called hump and spike periodic signal, explained by Rossby...

    Unresolved Wind-driven Shells and the Supersonic Velocity Dispersion in Giant H II Regions
    The presence of giant shells or loops in giant H II regions is clear witness to the mechanical energy input from massive stars. Here we evaluate the impact that...

    Unusual high-frequency oscillations in the Kepler δ Scuti star KIC 4840675
    We show that the star KIC 4840675 observed by Kepler is composed of three stars with a rapidly rotating A-type star and two solar-type fainter companions. The A...

    Unusual nanostructures of "lattice matched" InP on AlInAs
    We show that the morphology of the initial monolayers of InP on Al0.48In0.52As grown by metalorganic vapor-phase epitaxy does not follow the expected layer-by...

    Unusual Stokes V profiles during flaring activity of a delta sunspot
    Aims: We analyze a set of full Stokes profile observations of the flaring active region NOAA 10808. The region was recorded with the Vector-Spectromagnetograph...

    Unveiling Far-infrared Counterparts of Bright Submillimeter Galaxies Using PACS Imaging
    We present a search for Herschel-PACS counterparts of dust-obscured, high-redshift objects previously selected at submillimeter and millimeter wavelengths in...
  • Publication
    Unveiling low-ionization microstructures in planetary nebulae.
    (Hα+[NII])/[OIII] ratio images have been used to search for low-ionization small-scale structures in a sample of 258 planetary nebulae. Radially symmetrical...

    Unveiling optical signatures of outflows in accreting white dwarfs
    Accreting white dwarfs are known to show signatures of wind-type outflows in the ultraviolet. However, at optical wavelengths, wind detections have only been...

    Unveiling recurrent jets of the ULX Holmberg II X-1: evidence for a massive stellar-mass black hole?
    We report on the discovery of an apparent triple radio structure hidden inside the radio bubble of the ultraluminous X-ray source Holmberg II X-1. The...
