Height and Energy Evolution of X-ray Double Sources in a Solar Flare
Hanya Pan, Astrid M. Veronig, Rui Liu
In the standard model, magnetic reconnection at a vertical current sheet above the flare arcade is key to explaining many aspects of solar eruptions. The supra-arcade region is whe…
Height-dependent thermal properties of extreme-ultraviolet campfires in the quiet Sun
O. Podladchikova, A. Warmuth, L. Harra +30
Small-scale impulsive energy-release events are widely considered a key ingredient of quiet-Sun coronal heating. We quantified the thermal-energy content of extreme-ultraviolet (EU…
Coronal mass ejection arrival forecasting with the drag-based assimilation of satellite observations
Zaina Abu-Shaar, Tatiana Podladchikova, Astrid M. Veronig +2
Forecasting the arrival of coronal mass ejections (CMEs) is vital for protecting satellites, power systems, and human spaceflight. We present HELIOPANDA: Heliospheric Observer for…
Image calibration between the Extreme Ultraviolet Imagers on Solar Orbiter and the Solar Dynamics Observatory
Christoph Schirninger, Robert Jarolim, Astrid M. Veronig +6
To study and monitor the Sun and its atmosphere, various space missions have been launched in the past decades. With the rapid improvement in technology and different mission requi…
Magnetic structure and asymmetric eruption of a 500 Mm filament rooted in weak-field regions
Stefan Purkhart, Astrid M. Veronig, Robert Jarolim +2
We performed a detailed analysis of the magnetic structure and asymmetric eruption of a large (about 500 Mm) inverse S-shaped filament partially located in AR 13229 on February 24,…
Flares on TRAPPIST-1 reveal the spectrum of magnetic features on its surface
Valeriy Vasilyev, Nadiia Kostogryz, Alexander I. Shapiro +11
TRAPPIST-1 is an M8 dwarf hosting seven known exoplanets and is currently one of the most frequently observed targets of the James Webb Space Telescope (JWST). However, it is notor…
Extreme ultraviolet late-phase flares as observed by EVE and AIA on board the Solar Dynamics Observatory
Sascha Ornig, Astrid M. Veronig, Karin Dissauer
Context. Extreme ultraviolet (EUV) late-phase (ELP) flares exhibit a second peak in warm coronal emissions minutes to hours after the main peak of the flare. This phase is all but…
Coronal dimmings from active region 13664 during the May 2024 solar energetic events
Amaia Razquin, Astrid M. Veronig, Karin Dissauer +2
Coronal dimmings are regions of transiently reduced brightness in extreme ultraviolet (EUV) and soft X-ray (SXR) emissions associated with coronal mass ejections (CMEs), providing…
Deep learning image burst stacking to reconstruct high-resolution ground-based solar observations
Christoph Schirninger, Robert Jarolim, Astrid M. Veronig +1
Large aperture ground based solar telescopes allow the solar atmosphere to be resolved in unprecedented detail. However, observations are limited by Earths turbulent atmosphere, re…
Spatiotemporal evolution of UV pulsations and their connection to 3D magnetic reconnection and particle acceleration
Stefan Purkhart, Hannah Collier, Laura A. Hayes +3
Quasi-periodic pulsations (QPPs) are a common feature of impulsive solar flare emissions, yet their driving mechanism(s) remain unresolved. We study long-period (3.4 min) QPPs in t…
Conditioning of the solar corona due to large flares
Julia K. Thalmann, Manu Gupta, Astrid M. Veronig +1
We aim to better characterize the conditions of the solar corona, especially with respect to the occurrence of confined and eruptive flares. In this work, we model the coronal evol…
