Helioseismic Constraints: Past, Current, and Future Observations
Appourchaux, Thierry
I will review the history of the helioseismic observations since the beginning of the field. I will explain how each instrument was designed based upon the required observables, and to which modes these instruments are sensitive. The impact of these sensitivities on the rotation and structure inversion will be developed. I will conclude with what …
Localization of the Gamma-Ray Emission Region in the 1 September 2014 Behind-the-Limb Solar Flare According to the Fermi/LAT Data
Grechnev, V. V.; Kochanov, A. A.; Kiselev, V. I. +1 more
Since the launch of the Fermi mission in 2008, it has become possible to study high-energy solar γ-rays with an unprecedented imaging capability. In particular, the position of the >100 MeVγ-ray source can shed light on the origin of high-energy protons that is still controversial. However, the imaging of solar γ-ray sources with the Fermi Larg…
