Imaging individual active regions on the Sun's far side with improved helioseismic holography
Dan Yang, Laurent Gizon, Hélène Barucq
Helioseismic holography is a useful method to detect active regions on the Sun's far side and improve space weather forecasts. We aim to improve helioseismic holography by using a…
How to Estimate the Far-Side Open Flux using STEREO Coronal Holes
Stephan G. Heinemann, Manuela Temmer, Stefan J. Hofmeister +3
Global magnetic field models use as input synoptic data, which usually show "aging effects" as the longitudinal 360° information is not obtained simultaneously. Especially during t…
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…
Ghost Images in Helioseismic Holography? Toy Models in a Uniform Medium
Dan Yang
Helioseismic holography is a powerful technique used to probe the solar interior based on estimations of the 3D wavefield. Porter--Bojarski holography, which is a well-established…
