    The Thermal and Magnetic Structure of Umbral Dots from the Inversion of High-Resolution Full Stokes Observations
    This paper presents the analysis of high-resolution Stokes observations of eight different umbral dots in a sunspot. The spectra were recorded with the La Palma...

    The Thick Disk in the Galaxy NGC 4244 from S4G Imaging
    If thick disks are ubiquitous and a natural product of disk galaxy formation and/or evolution processes, all undisturbed galaxies that have evolved during a...

    The Three-dimensional Interaction between Emerging Magnetic Flux and a Large-Scale Coronal Field: Reconnection, Current Sheets, and Jets
    Using MHD numerical experiments in three dimensions, we study the emergence of a bipolar magnetic region from the solar interior into a model corona containing...

    The Three-dimensional Structure of a Sunspot Magnetic Field
    We report on observations of the three-dimensional structure of a sunspot magnetic field from the photosphere to the chromosphere, obtained with the new visible...

    The Three-dimensional Structure of an Active Region Filament as Extrapolated from Photospheric and Chromospheric Observations
    The three-dimensional structure of an active region filament is studied using nonlinear force-free field extrapolations based on simultaneous observations at a...

    The Tilt of the Fundamental Plane: Three-Quarters Structural Nonhomology, One-Quarter Stellar Population
    The variation of the mass-to-light M/L ratios of early-type galaxies as a function of their luminosities L is investigated. It is shown that the tilt β=0.27 (in...
