    On the Feedback from Super Stellar Clusters. I. The Structure of Giant H II Regions and H II Galaxies
    We review the structural properties of giant extragalactic H II regions and H II galaxies based on two-dimensional hydrodynamic calculations and propose an...

    On the functional form of the metallicity-giant planet correlation
    Context. It is generally accepted that the presence of a giant planet is strongly dependent on the stellar metallicity. A stellar mass dependence has also been...

    On the HU Aquarii planetary system hypothesis
    In this paper, we investigate the eclipse timing of the polar binary HU Aquarii that has been observed for almost two decades. Recently, Qian et al. attributed...

    On the Importance of the Nonequilibrium Ionization of Si IV and O IV and the Line of Sight in Solar Surges
    Surges are ubiquitous cool ejections in the solar atmosphere that often appear associated with transient phenomena like UV bursts or coronal jets. Recent...

    On the interpolation of model atmospheres and high-resolution synthetic stellar spectra
    We present tests carried out on optical and infrared stellar spectra to evaluate the accuracy of different types of interpolation. Both model atmospheres and...

    On the Inversion of Stokes Profiles with Local Stray-light Contamination
    Obtaining the magnetic properties of non-resolved structures in the solar photosphere is always challenging and problems arise because the inversion is carried...

    On the morphology of dust lanes in galactic bars
    The aim of our study is to use dynamical simulations to explore the influence of two important dynamical bar parameters, bar strength and bar pattern speed on...

    On the origin of magnetic driven winds and the structure of the galactic dynamo in isolated galaxies
    We investigate the build-up of the galactic dynamo and subsequently the origin of a magnetic driven outflow. We use a set-up of an isolated disc galaxy with a...

    On the Origin of the Type II Spicules: Dynamic Three-dimensional MHD Simulations
    Recent high temporal and spatial resolution observations of the chromosphere have forced the definition of a new type of spicule, "type II's," that are...
