Assessing the impact of background subtraction on a dust-free corona
Erika Palmerio, Cooper Downs, Phillip Hess +4
Context. White-light observations of the solar corona contain contributions from both the electron-scattered K-corona and the dust-scattered F-corona. Because the diffuse F-corona…
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…
Polarimetric Tomography Applied to Synthetic Multi-Spacecraft White-Light Images: Observing Coronal Mass Ejections in 3D
David Barnes, Erika Palmerio, Tanja Amerstorfer +7
A discrete tomography method has been developed that is able to reconstruct three-dimensional coronal mass ejection (CME) density structure. We test the method by producing synthet…
Testing the Flux Rope Paradigm for Coronal Mass Ejections Using a Three Spacecraft Encounter Event
Brian E. Wood, Phillip Hess
We present a 3-D morphological and field reconstruction of a coronal mass ejection (CME) from 2023 November 28, which hits three spacecraft near 1 au: Wind at Earth's L1 Lagrange p…
A Study on the Nested Rings CME Structure Observed by the WISPR Imager Onboard Parker Solar Probe
Shaheda Begum Shaik, Mark G. Linton, Sarah E. Gibson +5
Despite the significance of coronal mass ejections (CMEs) in space weather, a comprehensive understanding of their interior morphology remains a scientific challenge, particularly…
