Astrophysical Jets : what can we learn from Solar Ejections?

TL;DR

This paper explores potential analogies between solar ejections and astrophysical jets in microquasars and AGNs, aiming to leverage high-resolution solar observations to understand jet phenomena across different cosmic scales.

Contribution

It identifies shared characteristics between solar and astrophysical jets and suggests research avenues for cross-disciplinary insights, including possible analogies in ejection mechanisms.

Findings

Possible analogy between tearing instability in solar current sheets and plasma ejections in microquasars.

Shared properties between solar CMEs and astrophysical jets highlighted.

Research directions for cross-disciplinary understanding proposed.

Abstract

Ejections from the Sun can be observed with a higher resolution than in any other astrophysical object: can we build up on solar results and apply them to astrophysical objects? Aim of this work is to establish whether there is any analogy between solar ejections and ejections in microquasars and AGNs. Briefly reviewing jets properties from these objects and from the Sun, we point out some characteristics they share and indicate research areas where cross-breeeding between astrophysical and solar research is likely to be productive. Preliminary results of this study suggest, for instance, that there may be an analogy between blobs created by tearing instability in current sheets (CSs) associated with solar coronal mass ejections (CMEs) and quasi periodic ejections of plasma associated with large radio outbursts in microquasars.
