Solar inertial modes: Observations, identification, and diagnostic promise
Laurent Gizon, Robert H. Cameron, Yuto Bekki +10
The oscillations of a slowly rotating star have long been classified into spheroidal and toroidal modes. The spheroidal modes include the well-known 5-min acoustic modes used in he…
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…
C2 representations of the solar background coefficients for the model S-AtmoI
Florian Faucher, Damien Fournier, Ha Pham
We construct C2 representations of the background quantities that characterize the interior of the Sun and its atmosphere starting from the data-points of the standard solar model…
Effect of latitudinal differential rotation on solar Rossby waves: Critical layers, eigenfunctions, and momentum fluxes in the equatorial plane
L. Gizon, D. Fournier, M. Albekioni
Retrograde-propagating waves of vertical vorticity with longitudinal wavenumbers between 3 and 15 have been observed on the Sun with a dispersion relation close to that of classica…
Predicting frequency changes of global-scale solar Rossby modes due to solar cycle changes in internal rotation
C. R. Goddard, A. C. Birch, D. Fournier +1
Context. Large-scale equatorial Rossby modes have been observed on the Sun over the last two solar cycles. Aims. We investigate the impact of the time-varying zonal flows on the fr…
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…
