Pre-flare and active region plasma flows and structure seen by the short wavelength camera on SOLAR-C/EUVST
James McKevitt, Sarah Matthews, David H. Brooks +20
The mechanisms triggering solar flares and driving coronal heating occur across wide temperature ranges on small spatial scales and short timescales, making them difficult to obser…
The Non-Eruptive Reconfiguration of a Quiescent Filament After a Nearby Active Region Emergence
James McKevitt, Louise Harra, Gherardo Valori +13
The unpredictability of solar filament eruptions presents major challenges for forecasting space weather, as such eruptions frequently drive coronal mass ejections (CMEs) that impa…
Accessing the fine temporal scale of EUV brightenings and their quasi-periodic pulsations: 1 second cadence observations by Solar Orbiter/EUI
Daye Lim, Tom Van Doorsselaere, Nancy Narang +7
Small scale extreme ultraviolet (EUV) transient brightenings are observationally abundant and critically important to investigate. Determining whether they share the same physical…
Molecular Mobility of Extraterrestrial Ices: Surface Diffusion in Astrochemistry and Planetary Science
N. F. W. Ligterink, C. Walsh, H. M. Cuppen +12
Molecules are ubiquitous in space. They are necessary component in the creation of habitable planetary systems and can provide the basic building blocks of life. Solid-state proces…
CoSEE-Cat: A Comprehensive Solar Energetic Electron event Catalogue obtained from combined in situ and remote-sensing observations from Solar Orbiter -- Catalogue description and first statistical results
A. Warmuth, F. Schuller, R. Gómez-Herrero +39
(abridged) The acceleration of particles at the Sun and their propagation through interplanetary space are key topics in heliophysics. Specifically, solar energetic electrons (SEEs…
Active region upflows in various coronal structures and their coupling to the lower atmosphere
Yingjie Zhu, Louise Harra, Krzysztof Barczynski +13
Plasma upflows with a Doppler shift exceeding -10 km/s at active region (AR) boundaries are considered potential sources of the nascent slow solar wind. We investigate the driving…
A New Method of Deriving Doppler Velocities for Solar Orbiter SPICE
J. E. Plowman, D. M. Hassler, M. E. Molnar +7
This paper presents a follow-up to previous work on correcting PSF-induced Doppler artifacts in observations by the SPICE spectrograph on Solar Orbiter. In a previous paper, we dem…
A magnetic avalanche as the central engine powering a solar flare
L. P. Chitta, D. I. Pontin, E. R. Priest +17
Solar flares are the most powerful, magnetically driven, explosions in the heliosphere. The nature of magnetic energy release in the solar corona that heats the plasma and accelera…
Solar flares in the Solar Orbiter era: Short-exposure EUI/FSI observations of STIX flares
Hannah Collier, Laura A. Hayes, Stefan Purkhart +10
Aims: This paper aims to demonstrate the importance of short-exposure extreme ultraviolet (EUV) observations of solar flares in the study of particle acceleration, heating and ener…
Coronal hole picoflare jets are progenitors of both fast and Alfvénic slow solar wind
L. P. Chitta, Z. Huang, R. D'Amicis +19
Solar wind, classified by its bulk speed and the Alfvénic nature of its fluctuations, generates the heliosphere. The elusive physical processes responsible for the generation of th…
Spatial distributions of EUV brightenings in the quiet-Sun
C. J. Nelson, L. A. Hayes, D. Müller +16
The identification of large numbers of localised transient EUV brightenings, with small spatial scales, in the quiet-Sun corona has been one of the key early results from Solar Orb…
The observational evidence that all microflares that accelerate electrons to high energies are rooted in sunspots
Andrea Francesco Battaglia, Säm Krucker, Astrid M. Veronig +6
In general, large solar flares are more efficient at accelerating high-energy electrons than microflares. Nonetheless, we sometimes observe microflares that accelerate electrons to…
Post-Outburst Chemistry in a Very Low-Luminosity Object: Peculiar High Abundance of Nitric Oxide
B. M. Kulterer, S. F. Wampfler, N. F. W. Ligterink +7
Abridged: Very Low Luminosity Objects (VeLLOs) are deeply embedded, and extremely faint objects and are thought to be in the quiescent phase of the episodic accretion process. They…
Localising pulsations in the hard X-ray and microwave emission of an X-class flare
Hannah Collier, Laura A. Hayes, Sijie Yu +5
Aims: This work aims to identify the mechanism driving pulsations in hard X-ray (HXR) and microwave emission during solar flares. Here, by using combined HXR and microwave observat…
The existence of hot X-ray onsets in solar flares
Andrea Francesco Battaglia, Hugh Hudson, Alexander Warmuth +9
It is well known among the scientific community that solar flare activity often begins well before the main impulsive energy release. Our aim is to investigate the earliest phase o…
Two-horn quiescent prominence observed in H-alpha and MgII h&k lines with THEMIS and IRIS
Krzysztof Barczynski, Brigitte Schmieder, Bernard Gelly +2
Prominences are large magnetic structures in the corona filled by cool plasma with fast evolving fine structure. We aim to better understand the plasma conditions in the fine struc…
Evolution of dynamic fibrils from the cooler chromosphere to the hotter corona
Sudip Mandal, Hardi Peter, Lakshmi Pradeep Chitta +17
Dynamic fibrils (DFs) are commonly observed chromospheric features in solar active regions. Recent observations from the Extreme Ultraviolet Imager (EUI) aboard the Solar Orbiter h…
Picoflare jets power the solar wind emerging from a coronal hole on the Sun
L. P. Chitta, A. N. Zhukov, D. Berghmans +17
Coronal holes are areas on the Sun with open magnetic field lines. They are a source region of the solar wind, but how the wind emerges from coronal holes is not known. We observed…
