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…
A statistical study of propagating MHD kink waves in the quiescent corona

The Coronal Multi-channel Polarimeter (CoMP) has opened up exciting opportunities to probe transverse MHD waves in the Sun's corona. The archive of CoMP data is utilised to generat…
Weak damping of propagating MHD kink waves in the quiescent corona
Richard J. Morton, Ajay K. Tiwari, Tom Van Doorsselaere +1
Propagating transverse waves are thought to be a key transporter of Poynting flux throughout the Sun's atmosphere. Recent studies have shown that these transverse motions, interpre…
The Solar Orbiter Science Activity Plan: translating solar and heliospheric physics questions into action

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…
Mapping the magnetic field in the solar corona through magnetoseismology
Zihao Yang, Hui Tian, Steven Tomczyk +4
Magnetoseismology, a technique of magnetic field diagnostics based on observations of magnetohydrodynamic (MHD) waves, has been widely used to estimate the field strengths of oscil…
Global maps of the magnetic field in the solar corona
Zihao Yang, Christian Bethge, Hui Tian +10
Understanding many physical processes in the solar atmosphere requires determination of the magnetic field in each atmospheric layer. However, direct measurements of the magnetic f…
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…
