# A blowout jet associated with one obvious extreme-ultraviolet wave and one complicated coronal mass ejection event

## TL;DR

This study analyzes a solar blowout jet linked with an EUV wave and a complex CME, revealing magnetic flux emergence as the trigger and providing detailed multi-wavelength observations of the phenomena.

## Contribution

It offers new observational evidence of the association between blowout jets, EUV waves, and dual CME structures, supporting the double-CME blowout jet model.

## Key findings

- EUV wave appeared ahead of the jet top at 458-762 km/s.
- Dark material confirmed mini-filament eruption at the jet base.
- Two CME structures observed: narrow jet-shaped and bubble-shaped.

## Abstract

In this paper, we present a detailed analysis of a coronal blowout jet eruption which was associated with an obvious extreme-ultraviolet (EUV) wave and one complicated coronal mass ejection (CME) event based on the multi-wavelength and multi-view-angle observations from {\sl Solar Dynamics Observatory} and {\sl Solar Terrestrial Relations Observatory}. It is found that the triggering of the blowout jet was due to the emergence and cancellation of magnetic fluxes on the photosphere. During the rising stage of the jet, the EUV wave appeared just ahead of the jet top, lasting about 4 minutes and at a speed of 458 - \speed{762}. In addition, obvious dark material is observed along the EUV jet body, which confirms the observation of a mini-filament eruption at the jet base in the chromosphere. Interestingly, two distinct but overlapped CME structures can be observed in corona together with the eruption of the blowout jet. One is in narrow jet-shape, while the other one is in bubble-shape. The jet-shaped component was unambiguously related with the outwardly running jet itself, while the bubble-like one might either be produced due to the reconstruction of the high coronal fields or by the internal reconnection during the mini-filament ejection according to the double-CME blowout jet model firstly proposed by Shen et al. (2012b), suggesting more observational evidence should be supplied to clear the current ambiguity based on large samples of blowout jets in future studies.
