    Magnetic Flux Cancellation in the Moat of Sunspots: Results from Simultaneous Vector Spectropolarimetry in the Visible and the Infrared
    We analyze multiwavelength observations of the cancellation of a moving magnetic feature and a plage element at the outer edge of the moat of an isolated, round...

    Magnetic flux emergence in granular convection: radiative MHD simulations and observational signatures
    Aims:We study the emergence of magnetic flux from the near-surface layers of the solar convection zone into the photosphere. Methods: To model magnetic flux...

    Magnetic flux emergence into the solar photosphere and chromosphere
    Aims: We model the emergence of magnetized plasma across granular convection cells and the low atmosphere, including layers up to the mid-chromosphere. Methods...

    Magnetic flux in the inter-network quiet Sun from comparison with numerical simulations
    Khomenko et al. estimate the mean magnetic field strength of the quiet Sun to be 20 G. The figure is smaller than several existing estimates, and it comes from...

    Magnetic flux in the internetwork quiet Sun
    We report a direct comparison of the amplitudes of Stokes spectra of the Fe i 630 nm and 1.56 μm lines produced by realistic MHD simulations with simultaneous...

    Magnetic Flux, Heating, & Flaring: Clues from the Sun for Other Stars & Systems
    On the Sun, the presence of magnetic flux at the photosphere is closely linked to (1) steady heating of the overlying atmosphere and (2) transient brightenings...
