    Convectively driven vortex flows in the Sun
    We have discovered small whirlpools in the Sun, with a size similar to the terrestrial hurricanes (<0.5 Mm). The theory of solar convection predicts them, but...

    Instability and eruption of magnetic flux tubes in the solar convection zone
    We present a consistent model of storage, instability and dynamical eruption of magnetic flux tubes in the solar convection zone and underlying overshoot region...

    Phase difference between irradiance and velocity in low degree solar p-modes
    Phase differences between irradiance and full-disk velocity variations are derived for l = 0, 1, and 2 modes with order ranging from 11 up to 30 (1.8-4.3 mHz)...

    Quantum statistical corrections on the enhancement factor in solar fusion reactions
    The enhancement factor to the thermonuclear reaction rate in the center of the Sun is calculated using the Feynman-Kac path integral of the grand-canonical...

    Quiet Sun magnetism and Alfven waves as observed with Hinode
    The magnetic landscape of the polar region (Tsuneta et al, 2008) is characterized by vertical kilogauss patches with super-equipartition field strength, a...

    Rapid rotation of the solar interior
    Evidence for the rapid internal rotation of the sun obtained from Doppler shift measurements of the Fraunhofer absorption lines is reported. An improved version...

    Resolving the Tachocline Using Inversion of Rotational Splitting Derived from Fitting Very Long and Long Time Series
    We use rotation splittings derived from very long and long time series, namely 25.2, 12.6, and 6.3 yr long, computed by S. G. Korzennik independent methodology...

    Secular variations in the spectrum of solar p-modes
    The solar p-mode spectrum of very low l is measured with high accuracy for a long enough period of time so as to allow the search for solar cycle variations. In...

    Solar Interior: Emerging Magnetic Flux Tubes
    The magnetic field observed in the photosphere and at higher levels of the solar atmosphere is generated in the convective envelope that extends along the first...
