CME -Associated Energetic Ions at 0.23 AU -- Consideration of the Auroral Pressure Cooker Mechanism Operating in the Low Corona as a Possible Energization Process

TL;DR

This paper proposes that a pressure cooker mechanism in the low corona may energize particles during CME events, linking solar and planetary auroral processes to explain observed energetic particle populations.

Contribution

It introduces a novel energization process in the low corona that connects CME development with auroral phenomena and energetic particle acceleration.

Findings

CME-associated energetic ions are linked to auroral pressure mechanisms.

The process may explain Type III radio bursts and prompt energetic particles.

A common mechanism in solar and planetary auroral regions is proposed.

Abstract

We draw a comparison between a solar energetic particle event associated with the release of a slow coronal mass ejection close to the sun, and the energetic particle population produced in high current density field-aligned current structures associated with auroral phenomena in planetary magnetospheres. We suggest that this process is common in CME development and lift-off in the corona, and may account for the electron populations that generate Type III radio bursts, as well as for the prompt energetic ion and electron populations typically observed in interplanetary space.
