Energy Evolution from the Chromosphere to the Heliosphere in the 2021 October 28 Solar Eruption
Katharine K. Reeves, Daniel B. Seaton, Cynthia Cattell +20
We perform a detailed study of the energetics for a well-observed solar eruption and flare that occurred on 28 October 2021. This event included a GOES class X1.0 flare, a global E…
A multiple spacecraft detection of the 2 April 2022 M-class flare and filament eruption during the first close Solar Orbiter perihelion
M. Janvier, S. Mzerguat, P. R. Young +56
The Solar Orbiter mission completed its first remote-sensing observation windows in the spring of 2022. On 2/4/2022, an M-class flare followed by a filament eruption was seen both…
Source positions of an interplanetary type III radio burst and anisotropic radio-wave scattering
Xingyao Chen, Eduard P. Kontar, Nicolina Chrysaphi +7
Interplanetary solar radio type III bursts provide the means for remotely studying and tracking energetic electrons propagating in the interplanetary medium. Due to the lack of dir…
Observations of magnetic reconnection and particle acceleration locations in solar coronal jets
Yixian Zhang, Sophie Musset, Lindsay Glesener +2
We present a multi-wavelength analysis of two flare-related jets on November 13, 2014, using data from SDO/AIA, RHESSI, Hinode/XRT, and IRIS. Unlike most coronal jets where hard X-…
The Spectrometer Telescope for Imaging X-rays (STIX) on Solar Orbiter
Laura A. Hayes, Sophie Musset, Daniel M üller +1
The Spectrometer/Telescope for Imaging X-rays (STIX) is one of the 10 instruments on-board the scientific payload of ESA's Solar Orbiter mission. STIX provides hard X-ray imaging s…
On the faintest solar coronal hard X-rays observed with FOXSI
Juan Camilo Buitrago-Casas, Lindsay Glesener, Steven Christe +23
Solar nanoflares are small eruptive events releasing magnetic energy in the quiet corona. If nanoflares follow the same physics as their larger counterparts, they should emit hard…
Simulations of radio-wave anisotropic scattering to interpret type III radio bursts measurements by Solar Orbiter, Parker Solar Probe, STEREO and Wind
S. Musset, M. Maksimovic, E. Kontar +9
We use multi-spacecraft observations of invididual type III radio bursts in order to calculate the directivity of the radio emission, to be compared to the results of ray-tracing s…
Connecting solar flare hard X-ray spectra to in situ electron spectra. A comparison of RHESSI and STEREO/SEPT observations
Nina Dresing, A. Warmuth, F. Effenberger +4
We compare the characteristics of flare-accelerated energetic electrons at the Sun with those injected into interplanetary space. We have identified 17 energetic electron events we…
STIX X-ray microflare observations during the Solar Orbiter commissioning phase
Andrea Francesco Battaglia, Jonas Saqri, Paolo Massa +34
The Spectrometer/Telescope for Imaging X-rays (STIX) is the HXR instrument onboard Solar Orbiter designed to observe solar flares over a broad range of flare sizes, between 4-150 k…
Constraints on the acceleration region of type III radio bursts from decimetric radio spikes and faint X-ray bursts
Sophie Musset, Eduard Kontar, Lindsay Glesener +2
We study the release of energy during the gradual phase of a flare, characterized by faint bursts of non-thermal hard X-ray (HXR) emission associated with decimetric radio spikes a…
FOXSI-2 Solar Microflares II: Hard X-ray Imaging Spectroscopy and Flare Energetics
Juliana T. Vievering, Lindsay Glesener, P. S. Athiray +7
We study the nature of energy release and transfer for two sub-A class solar microflares observed during the second flight of the Focusing Optics X-ray Solar Imager (FOXSI-2) sound…
