    On the Influence of the Environment on the Star Formation Rates of a Sample of Galaxies in Nearby Compact Groups
    We present the results of a study of the star formation rates (SFRs) of a sample of disk galaxies in nearby compact groups compared with the SFRs of a sample of...

    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 Inversion of the Scattering Polarization and the Hanle Effect Signals in the Hydrogen Lyα Line
    Magnetic field measurements in the upper chromosphere and above, where the gas-to-magnetic pressure ratio β is lower than unity, are essential for understanding...

    On the Ionizing Continuum in Active Galactic Nuclei: Clues from the Infrared Space Observatory
    The Infrared Space Observatory (ISO) coronal line spectrum of the brightest Seyfert galaxies from the CfA sample is presented and modeled. ISO observations of...

    On the Kinematic Separation of Field and Cluster Stars across the Bulge Globular NGC 6528
    We present deep and precise multi-band photometry of the Galactic bulge globular cluster NGC 6528. The current data set includes optical and near-infrared...

    On The Kinematics of Multiple-Shell Planetary Nebulae. I. Data and Expansion Velocities
    We present spatially resolved echelle spectroscopy, obtained at high spectral resolution, for 15 multiple-shell planetary nebulae. Most exhibit faint detached...

    On the Magnetic Field of Off-limb Spicules
    Determining the magnetic field related to solar spicules is vital for developing adequate models of these plasma jets, which are thought to play a key role in...

    On the Magnetic Nature of an Exploding Granule as Revealed by Sunrise/IMaX
    We study the photospheric evolution of an exploding granule observed in the quiet Sun at high spatial (∼0"3) and temporal (31.5 s) resolution by the imaging...

    On the Magnetic Nature of Quiet-Sun Chromospheric Grains
    Ca II K grains, i.e., intermittent, short-lived (about 1 minute), periodic (2-4 minutes), pointlike chromospheric brightenings, are considered to be the...
