Cause and Kinematics of a Jet-Like CME

TL;DR

This study analyzes a solar jet and its association with a narrow CME, revealing the jet's path along open magnetic field lines and its kinematic properties, challenging the typical understanding of CME origins.

Contribution

It provides multi-viewpoint and multi-wavelength analysis linking a solar jet to a narrow CME, with potential field extrapolation confirming the magnetic pathway.

Findings

Jet associated with a 25-degree wide CME at 450 km/s

Jet follows open magnetic field lines from the source region

Potential field extrapolation confirms magnetic pathway for jet escape

Abstract

In this article, we present the multi-viewpoint and multi-wavelength analysis of an atypical solar jet based on the data from Solar Dynamics Observatory, SOlar, and Heliospheric Observatory, and Solar TErrestrial RElations Observatory. It is usually believed that the coronal mass ejections (CMEs) are developed from the large scale solar eruptions in the lower atmosphere. However, the kinematical and spatial evolution of the jet on 2013 April 28 guide us that the jet was clearly associated with a narrow CME having a width of approx 25 degrees with a speed of 450 km/s. To better understand the link between the jet and the CME, we did the coronal potential field extrapolation from the line of sight magnetogram of the AR. The extrapolations present that the jet eruption follows exactly the same path of the open magnetic field lines from the source region which provides the route for the jet material to escape from the solar surface towards the outer corona.
