Helioseismological determination of the subsurface spatial spectrum of solar convection: Demonstration using numerical simulations
Vincent G. A. Böning, Aaron C. Birch, Laurent Gizon +1
Understanding convection is important in stellar physics, for example as an input in stellar evolution models. Helioseismic estimates of convective flow amplitudes in deeper region…
Solar east-west flow correlations that persist for months at low latitudes are dominated by active region inflows
Chris S. Hanson, Thomas L. Duvall, Aaron C. Birch +2
Context: Giant-cell convection is believed to be an important component of solar dynamics. For example, it is expected to play a crucial role in maintaining the Sun's differential…
Acoustic wave propagation through solar granulation: Validity of effective-medium theories, coda waves
P. -L. Poulier, D. Fournier, L. Gizon +1
Context. The frequencies, lifetimes, and eigenfunctions of solar acoustic waves are affected by turbulent convection, which is random in space and in time. Since the correlation ti…
Characterizing the spatial pattern of solar supergranulation using the bispectrum
Vincent G. A. Böning, Aaron C. Birch, Laurent Gizon +2
Context. The spatial power spectrum of supergranulation does not fully characterize the underlying physics of turbulent convection. For example, it does not describe the non-Gaussi…
Time-distance helioseismology of solar Rossby waves
Zhi-Chao Liang, Laurent Gizon, Aaron C. Birch +1
Context. Solar Rossby waves (r modes) have recently been discovered in the near-surface horizontal flow field using the techniques of granulation-tracking and ring-diagram analysis…
Solar meridional circulation from twenty-one years of SOHO/MDI and SDO/HMI observations: Helioseismic travel times and forward modeling in the ray approximation
Zhi-Chao Liang, Laurent Gizon, Aaron C. Birch +2
The south-north travel-time differences are measured by applying time-distance helioseismology to the MDI and HMI medium-degree Dopplergrams covering May 1996-April 2017. Our data…
