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…
Signal and noise in helioseismic holography
Laurent Gizon, Damien Fournier, Dan Yang +2
Helioseismic holography is an imaging technique used to study heterogeneities and flows in the solar interior from observations of solar oscillations at the surface. Holograms cont…
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…
Global-scale equatorial Rossby waves as an essential component of solar internal dynamics
Björn Löptien, Laurent Gizon, Aaron C. Birch +5
The Sun's complex dynamics is controlled by buoyancy and rotation in the convection zone and by magnetic forces in the atmosphere and corona. While small-scale solar convection is…
