A Solar Coronal Jet Event Triggers a Coronal Mass Ejection

Abstract

We present the multi-point and multi-wavelength observation and analysis on a solar coronal jet and coronal mass ejection (CME) event in this paper. Employing the GCS model, we obtained the real (three-dimensional) heliocentric distance and direction of the CME and found it propagate in a high speed over 1000 km s −1 . The jet erupted before and shared the same source region with the CME. The temporal and spacial relationship between them guide us the possibility that the jet triggered the CME and became its core. This scenario could promisingly enrich our understanding on the triggering mechanism of coronal mass ejections and their relations with coronal large-scale jets. On the other hand, the magnetic field configuration of the source region observed by the SDO/HMI instrument and the offlimb inverse Y-shaped configuration observed by SDO/AIA 171 Å passband, together provide the first detailed observation on the three-dimensional reconnection process of large-scale jets as simulated in Pariat et al. 2009. The erupting process of the jet highlights that filament-like materials are important during the eruption not only of small-scale X-ray jets (Sterling et al. 2015) but also probably of large-scale EUV jets. Based on our observation and analysis, we propose a most possible mechanism for the whole event with a blob structure overlaying the three-dimensional structure of the jet to describe the interaction between the jet and the CME.

Flare-related Recurring Active Region Jets: Evidence for Very Hot Plasma

“…The impulsive and collimated events which originate at the edges of active regions and/or sunspots are known as active region jets (AR jets). Numerous studies have been dedicated to understanding the relationship between AR jets and other phenomena such as micro-flares (Chae et al, 1999;Chifor et al, 2008), flares (Chen, Ip, and Innes, 2013;Krucker et al, 2008), hard X-ray emission (Bain and Fletcher, 2009;Krucker et al, 2011;Glesener, Krucker, and Lin, 2012), Coronal Mass Ejections (CMEs) (Liu et al, 2015;Panesar, Sterling, and Moore, 2016;Miao et al, 2017;Sterling, Moore, and Panesar, 2018), type-III radio bursts (Kundu et al, 1995;Raulin et al, 1996;Klassen, Gómez-Herrero, and Heber, 2011;Innes, Cameron, and Solanki, 2011;Chandra et al, 2015;Mulay et al, 2016) and impulsive solar energetic particle events (Nitta et al, 2006;Pick et al, 2006;Nitta et al, 2008;Wang, Pick, and Mason, 2006;Nitta et al, 2015).…”

Blowout jets and impulsive eruptive flares in a bald-patch topology

“…Jets, standard or blowout, have been observed in Hα or EUV in association with white-light CMEs whose eruption can be traced back to the same location in an AR (Liu et al 2005;Liu 2008;Liu et al 2015;Li et al 2015). In particular, Yan et al (2012) studied two successive flares of X-ray class M that occurred in AR 10484 on 22 October 2003.…”

Solar Dynamical Processes II

“…It has been reported that the eruption of prominence often leads to a CME [95]. Liu et al [96] observed and analyzed the data obtained from SDO, SOHO and STEREO and suggested that solar jet event can trigger a high -speed CME. Their observation was consistent with the three -dimensional model of solar jets proposed by Pariat et al [71].…”
