3D Modeling of Solar Oscillations with Hybridizable Discontinuous Galerkin Method
Florian Faucher, Ha Pham, Damien Fournier +5
With increasing quantity and quality of solar observations, it becomes essential to account for three-dimensional heterogeneities in wave modeling for seismic data interpretation.…
Swaying oscillations in Rayleigh-Bénard convection cast new light on solar convection
F. Kupka, D. Fabbian, F. Zaussinger +2
Horizontally-periodic Boussinesq Rayleigh-Bénard Convection (RBC) is a simple model system to study the formation of large-scale structures in turbulent convective flows. We perfor…
Evaluating Solar Wind Forecast Using Magnetic Maps That Include Helioseismic Far-Side Information
Stephan G. Heinemann, Dan Yang, Shaela I. Jones +5
To model the structure and dynamics of the heliosphere well enough for high-quality forecasting, it is essential to accurately estimate the global solar magnetic field used as inne…
Oscillations of the solar photospheric magnetic field caused by the m = 1 high-latitude inertial mode
Stephan G. Heinemann, Zhi-Chao Liang, Laurent Gizon
Periodic oscillations at 338 nHz in the Earth frame are observed at high latitudes in direct Doppler velocity measurements. These oscillations correspond to the high-latitude…
Numerical simulations of oscillations for axisymmetric solar backgrounds with differential rotation and gravity
Ha Pham, Florian Faucher, Damien Fournier +2
Local helioseismology comprises of imaging and inversion techniques employed to reconstruct the dynamic and interior of the Sun from correlations of oscillations observed on the su…
Linear toroidal-inertial waves on a differentially rotating sphere with application to helioseismology: Modeling, forward and inverse problems
Tram Thi Ngoc Nguyen, Damien Fournier, Laurent Gizon +1
This paper develops a mathematical framework for interpreting observations of solar inertial waves in an idealized setting. Under the assumption of purely toroidal linear waves on…
Structure and Dynamics of the Sun's Interior Revealed by Helioseismic and Magnetic Imager
Alexander Kosovichev, Sarbani Basu, Yuto Bekki +43
High-resolution helioseismology observations with the Helioseismic and Magnetic Imager (HMI) onboard Solar Dynamics Observatory (SDO) provide a unique three-dimensional view of the…
Observations of eigenfunctions of solar inertial modes using local correlation tracking of magnetic features
Neelanchal Joshi, Zhi-Chao Liang, Damien Fournier +1
Solar inertial modes are quasi-toroidal modes of the Sun that are of practical interest as they allow probing the deep convection zone. Since 2010, solar images of the photospheric…
