    Green's Functions for Far-Side Seismic Images: A Polar-Expansion Approach
    We have computed seismic images of magnetic activity on the far surface of the Sun by using a seismic-holography technique. As in previous works, the method is...

    Helioseismic evidence of two solar granulation timescales
    The signature of two different scales of solar granulation in the power spectrum of disk integrated irradiance time series is presented. The fitted timescales...

    Helioseismic Holography of Simulated Sunspots: Magnetic and Thermal Contributions to Travel Times
    Wave propagation through sunspots involves conversion between waves of acoustic and magnetic character. In addition, the thermal structure of sunspots is very...

    Influence of Low-Degree High-Order p-Mode Splittings on the Solar Rotation Profile
    The solar rotation profile is well constrained down to about 0.25 R &sun; thanks to the study of acoustic modes. Since the radius of the inner turning point of...
