Author: Kazuhiro INAGAKIRecent numerical simulation revealed that large-scale flow is generated in a rotating system with inhomogeneous helicity. However its mechanism was not examined in terms of the Reynolds stress transport. In this study, the large-e ... more
Author: Frank HillGONG (Global Oscillation Network Group) is now 20 years old and continues to reliably provide data for the international helioseismology community. In addition the role of GONG has expanded to provide data as input to a number of ... more
Author: Anthony YeatesWhat if there were a way to identify **where** the magnetic helicity is concentrated within a three- dimensional magnetic field? At first sight this question appears meaningless, since magnetic helicity is an integral over the who ... more
Author: Carlo AlbertAssuming a simple data-generating model of the type "pure harmonics plus noise" and applying Bayesian inference techniques has two advantages over Fourier analysis: (i) lines that are separated by less than the Fourier resolution ... more
Author: Peter LeitnerSimulations of the solar convection including radiation transport allow us to examine and track photospheric shock waves in detail unparalleled by direct observation. It is still not clear which processes trigger shocks and how si ... more
Author: Vincent BöningIn this study, we present first inversion results for deep meridional flow using spherical Born approximation kernels and time-distance helioseismology.
The computation of Born approximation kernels for flows has only recently be ... more
Author: Astrid VeronigIn this talk, I review the availability and use of ground-based observations for the study of the solar sources of space weather. High-cadence full-disk imaging in the H-alpha spectral line provides us with a valuable means to ide ... more
