    Continuum Intensity and [O I] Spectral Line Profiles in Solar 3D Photospheric Models: The Effect of Magnetic Fields
    The importance of magnetic fields in three-dimensional (3D) magnetoconvection models of the Sun’s photosphere is investigated in terms of their influence on the...

    Convective Wavelength Shifts in the Spectra of Late-Type Stars
    We present ultrahigh-resolution spectra for a set of nearby F-G-K stars on, or close to, the main sequence. The wavelength shifts of stellar lines relative to...

    Convectively Driven Vortex Flows in the Sun
    We have discovered small whirlpools in the Sun, with a size similar to terrestrial hurricanes (

    Converging Flows in the Penumbra of a δ Sunspot
    Doppler velocities in the penumbra of a δ-configuration sunspot observed near the limb indicate flows that converge upon the line separating locally positive...

    Converting Hα Luminosities into Star Formation Rates
    Star formation rates (SFRs) of galaxies are commonly calculated by converting the measured Hα luminosities (LHα) into current SFRs. This conversion is based on...

    Convolutional Neural Networks and Stokes Response Functions
    In this work, we study the information content learned by a convolutional neural network (CNN) when trained to carry out the inverse mapping between a database...

    Cool Gas and Massive Stars: The Nuclear Ring in M100
    The SAURON integral-field spectrograph was used to observe the central area of the barred spiral galaxy M100 (NGC 4321). M100 contains a nuclear ring of star...
