Signatures of magnetic reconnection in solar eruptive flares: A multi-wavelength perspective

TL;DR

This paper reviews multi-wavelength observations of solar flares, emphasizing magnetic reconnection signatures, especially from RHESSI X-ray data, and discusses challenges and anomalies in the standard flare model.

Contribution

It provides a comprehensive review of recent multi-wavelength observations, highlighting the role of X-ray emissions in understanding magnetic reconnection in solar flares.

Findings

X-ray emissions from coronal loops support the magnetic reconnection model.

Some observations challenge the canonical flare picture.

Future observations are needed to resolve existing discrepancies.

Abstract

In this article, we review some key aspects of a multi-wavelength flare which have essentially contributed to form a standard flare model based on the magnetic reconnection. The emphasis is given on the recent observations taken by the Reuven Ramaty High Energy Solar Spectroscopic Imager (RHESSI) on the X-ray emission originating from different regions of the coronal loops. We also briefly summarize those observations which do not seem to accommodate within the canonical flare picture and discuss the challenges for future investigations.
