DEM analysis of the 6 September 2011 large-scale coronal wave
Amaia Razquin, Astrid M. Veronig, Karin Dissauer
Large-scale coronal waves are globally propagating intensity enhancements in extreme-ultraviolet (EUV) and soft X-ray (SXR) observations, associated with solar flares and coronal m…
Investigating potential benefits of future sub-L1 missions with STEREO-A
Eva Weiler, Emma E. Davies, Christian Möstl +4
We present the first statistical study of geomagnetic storm forecasting using in situ data from the STEREO-A spacecraft as a sub-L1 monitor. Between November 2022 and June 2024, ST…
Chromospheric magnetic field extrapolations reveal the flux-rope configuration of a solar filament
Robert Jarolim, João M. da Silva Santos, Matthias Rempel +5
Solar eruptions are powered by the release of magnetic energy stored in the lower solar atmosphere, but the pre-eruptive magnetic configuration of filament channels remains difficu…
Investigation of the Two-Dimensional Velocity Field of the Large-Scale Coronal Wave from September 6, 2011 using the SOLERwave Tool
Markus Baumgartner-Steinleitner, Astrid M. Veronig, Karin Dissauer +1
We investigate the two-dimensional velocity field of the fast and complex large-scale coronal wave observed on September 6, 2011. We use both a classical perturbation profile appro…
A single power law for the TRAPPIST-1 flare distribution across four orders of magnitude in energy
Valeriy Vasilyev, Alexander I. Shapiro, Nadiia Kostogryz +10
TRAPPIST-1 is an ultra-cool dwarf that flares frequently. These flares shape the surrounding planets' high-energy irradiation environments, with consequences for atmospheric chemis…
Stellar Coronal Mass Ejections with HWO: A Science Case Concept
R. O. Parke Loyd, James Paul Mason, Ivey Davis +3
The primary mission of the Habitable World Observatory (HWO) will be to constrain the prevalence of life on Earth-like planets. These planets will be subject to impacts by energeti…
