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…

Observation and Modeling of Shear Evolution of Post-reconnection Flare Loops

Drake Osaben, Jiong Qiu, Dana W. Longcope

A solar flare releases magnetic energy by reconnecting field lines across a current sheet, thereby allowing their relaxation to a lower energy state. The maximum possible energy is…

Fine Structures of Tiny Quiet Sun Jets Observed by Solar Orbiter and Big Bear Solar Observatory

Jeongwoo Lee, Dana Longcope, Junmu Youn +3

We present the first joint high-resolution observations of small-scale EUV jets using Solar Orbiter(SolO)'s Extreme Ultraviolet Imager and High Resolution Imager (HRI) and H ima…

A Model for Gradual Phase Heating Driven by MHD Turbulence in Solar Flares

William Ashfield, Dana Longcope

Coronal flare emission is commonly observed to decay on timescales longer than those predicted by impulsively-driven, one-dimensional flare loop models. This discrepancy is most ap…

Connecting Chromospheric Condensation Signatures to Reconnection Driven Heating Rates in an Observed Flare

William H. Ashfield, Dana W. Longcope, Chunming Zhu +1

Observations of solar flare reconnection at very high spatial and temporal resolution can be made indirectly at the footpoints of reconnected loops into which flare energy is depos…

Probing the Physics of the Solar Atmosphere with the Multi-slit Solar Explorer (MUSE): II. Flares and Eruptions

Mark C. M. Cheung, Juan Martínez-Sykora, Paola Testa +25

Current state-of-the-art spectrographs cannot resolve the fundamental spatial (sub-arcseconds) and temporal scales (less than a few tens of seconds) of the coronal dynamics of sola…
