Energetic Proton Back-Precipitation onto the Solar Atmosphere in Relation to Long-Duration Gamma-Ray Flares

Adam Hutchinson, Silvia Dalla, Timo Laitinen +4

Gamma-ray emission during long-duration gamma-ray flare (LDGRF) events is thought to be caused mainly by 300 MeV protons interacting with the ambient plasma at or near the photo…

The Solar Orbiter Science Activity Plan: translating solar and heliospheric physics questions into action

I. Zouganelis, A. De Groof, A. P. Walsh +182

Solar Orbiter is the first space mission observing the solar plasma both in situ and remotely, from a close distance, in and out of the ecliptic. The ultimate goal is to understand…

Nanoflare Diagnostics from Magnetohydrodynamic Heating Profiles

Kalman J. Knizhnik, Will T. Barnes, Jeffrey W. Reep +1

The nanoflare paradigm of coronal heating has proven extremely promising for explaining the presence of hot, multi-million degree loops in the solar corona. In this paradigm, local…

Analysis of the Helical Kink Stability of Differently Twisted Magnetic Flux Ropes

Marta Florido-Llinas, Teresa Nieves-Chinchilla, Mark G. Linton

Magnetic flux ropes (MFRs) are usually considered to be the magnetic structure that dominates the transport of helicity from the Sun into the heliosphere. They entrain a confined p…

Connecting Atmospheric Properties and Synthetic Emission of Shock Waves Using 3D RMHD Simulations of Quiet Sun

Viacheslav M. Sadykov, Irina N. Kitiashvili, Alexander G. Kosovichev +1

We analyze the evolution of shock waves in high-resolution 3D radiative MHD simulations of the quiet Sun and their synthetic emission characteristics. The simulations model the dyn…

Solar Flare Arcade Modelling: Bridging the gap from 1D to 3D Simulations of Optically Thin Radiation

Graham S. Kerr, Joel C. Allred, Vanessa Polito

Solar flares are 3D phenomenon but modelling a flare in 3D, including many of the important processes in the chromosphere, is a computational challenge. Accurately modelling the ch…

Hot X-ray Onsets of Solar Flares

Hugh S. Hudson, Paulo J. A. Simoes, Lyndsay Fletcher +2

The study of the localized plasma conditions before the impulsive phase of a solar flare can help us understand the physical processes that occur leading up to the main flare energ…

Inferences About the Magnetic Field Structure of a CME with Both In Situ and Faraday Rotation Constraints

Brian E. Wood, Samuel Tun-Beltran, Jason E. Kooi +2

On 2012 August 2, two CMEs (CME-1 and CME-2) erupted from the west limb of the Sun as viewed from Earth, and were observed in images from the white light coronagraphs on the SOHO a…
