X-ray Plasma Ejections and their association with other solar-activity phenomena

TL;DR

This study analyzes the relationship between X-ray Plasma Ejections and other solar phenomena like flares and CMEs, revealing that different subclasses of XPEs are linked to distinct solar activity characteristics.

Contribution

The paper introduces a new catalogue of XPEs and demonstrates their varied associations with flares and CMEs, highlighting different underlying physical processes.

Findings

Different subclasses of XPEs have varying association levels with flares and CMEs.

Flares and CMEs linked to different XPE subclasses exhibit distinct features.

XPEs may represent different physical processes depending on their subclass.

Abstract

Recently developed in Wroclaw, a new catalogue of X-ray Plasma Ejections (XPEs) observed by the Soft X-ray Telescope onboard Yohkoh, is a very useful tool for some statistical studies. We investigated the association of XPEs with solar flares and coronal mass ejections (CMEs). We found that particular subclasses of XPEs show different levels of association. Moreover, flares and CMEs associated with different subclasses of XPEs show distinctly different characteristics. We conclude that the event that we call 'X-ray Plasma Ejection' can be a manifestation of different physical processes.
