Journal ArticleDOI
The Helioseismic and Magnetic Imager (HMI) Vector Magnetic Field Pipeline: Overview and Performance
J. Todd Hoeksema,Yang Liu,Keiji Hayashi,Xudong Sun,Jesper Schou,Jesper Schou,Sebastien Couvidat,Aimee A. Norton,Monica G. Bobra,Rebecca Centeno,K. D. Leka,Graham Barnes,Michael Turmon +12 more
TL;DR: In this article, the Helioseismic and Magnetic Imager (HMI) active region patches (HARPs) are used to track the location and shape of magnetic regions throughout their lifetime.
Journal ArticleDOI
Magnetism, dynamo action and the solar-stellar connection
TL;DR: Observations and theory of magnetism in the Sun and other stars are reviewed, with a partial focus on the “Solar-stellar connection”: ways in which studies of other stars have influenced the authors' understanding of theSun and vice versa.
Journal ArticleDOI
Multi-Scale Gaussian Normalization for Solar Image Processing
Huw Morgan,Miloslav Druckmüller +1 more
TL;DR: A very efficient process is described here, which is based on localised normalising of the data at many different spatial scales and reveals information at the finest scales whilst maintaining enough of the larger-scale information to provide context.
Journal ArticleDOI
Observing the release of twist by magnetic reconnection in a solar filament eruption
Zhike Xue,Xiaoli Yan,Xin Cheng,Liheng Yang,Yingna Su,Bernhard Kliem,Bernhard Kliem,Jun Zhang,Zhong Liu,Yi Bi,Yongyuan Xiang,Kai Yang,Li Zhao +12 more
TL;DR: Evidence of fast reconnection in a solar filament eruption is presented using high-resolution H-alpha images from the New Vacuum Solar Telescope, supplemented by extreme ultraviolet observations, to demonstrate a new role for reconnections in solar eruptions: the release of magnetic twist.
Journal ArticleDOI
On the prevalence of small-scale twist in the solar chromosphere and transition region.
B. De Pontieu,L. Rouppe van der Voort,Scott W. McIntosh,Tiago M. D. Pereira,Mats Carlsson,Viggo Hansteen,H. Skogsrud,James R. Lemen,A. M. Title,Paul Boerner,Neal E. Hurlburt,T. D. Tarbell,Jean-Pierre Wuelser,E. E. De Luca,L. Golub,Sean McKillop,Katharine K. Reeves,Steven H. Saar,Paola Testa,Hui Tian,Charles C. Kankelborg,S. Jaeggli,Lucia Kleint,Juan Martinez-Sykora +23 more
TL;DR: High-resolution IRIS observations with NASA’s Interface Region Imaging Spectrograph reveal a chromosphere and TR that is replete with twist or torsional motions on sub–arc second scales, occurring in active regions, quiet Sun regions, and coronal holes alike.
