Parallel plasma loops and the energization of the solar corona
Hardi Peter, Lakshmi Pradeep Chitta, Feng Chen +15
The outer atmosphere of the Sun is composed of plasma heated to temperatures well in excess of the visible surface. We investigate short cool and warm (<1 MK) loops seen in the cor…
Mapping Solar Magnetic Fields from the Photosphere to the Base of the Corona
Ryohko Ishikawa, Javier Trujillo Bueno, Tanausu del Pino Aleman +25
Routine ultraviolet imaging of the Sun's upper atmosphere shows the spectacular manifestation of solar activity; yet we remain blind to its main driver, the magnetic field. Here we…
Untangling the global coronal magnetic field with multiwavelength observations
S. E. Gibson, A. Malanushenko, G. de Toma +16
Magnetism defines the complex and dynamic solar corona. Coronal mass ejections (CMEs) are thought to be caused by stresses, twists, and tangles in coronal magnetic fields that buil…
Critical Science Plan for the Daniel K. Inouye Solar Telescope (DKIST)
Mark P. Rast, Nazaret Bello González, Luis Bellot Rubio +84
The Daniel K. Inouye Solar Telescope (DKIST) will revolutionize our ability to measure, understand and model the basic physical processes that control the structure and dynamics of…
The drivers of active region outflows into the slow solar wind
David H. Brooks, Amy R. Winebarger, Sabrina Savage +13
Plasma outflows from the edges of active regions have been suggested as a possible source of the slow solar wind. Spectroscopic measurements show that these outflows have an enhanc…
