A Blowout Jet Associated with One Obvious Extreme-ultraviolet Wave and One Complicated Coronal Mass Ejection Event

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 Solar Dynamics Observatory and 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 -762 km s −1 . 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 , suggesting more observational evidence should be supplied to clear the current ambiguity based on large samples of blowout jets in future studies.

CME Productive and Non-productive Recurring Jets Near an Active Region AR11176

“…According to the twin CME model of Shen et al (2012), a single blow-out jet drags two CMEs in the solar atmosphere as jet-like CME and bubble-like CME. This model is supported by many observational events (e.g., Alzate and Morgan, 2016;Miao et al, 2018Miao et al, , 2019Solanki et al, 2019;Duan et al, 2019). The study, observations, and analysis of these coupled events (Jet and CME) can give better insight to understand the multi-scale eruptive phenomena in the solar atmosphere and their relation in the interplanetary space.…”

“…This miniature version of the mini-filament eruption produces jets likewise as the large filament eruption produces coronal mass ejections (CMEs). Sometimes, the large-scale plasma motions in the form of reconnection driven jets also form the coronal mass ejections (CMEs) in the outer solar atmosphere (e.g., Shen et al, 2012;Alzate and Morgan, 2016;Miao et al, 2018Miao et al, , 2019Solanki et al, 2019;Duan et al, 2019).…”

Observation and modelling of solar jets

“…Observations suggested that solar jets cause not only narrow jetlike CMEs [164] (figure 9a), but also standard broad CMEs with a typical three-part structure [240]. Sometimes, paired narrow and broad CMEs can be simultaneously launched by a single blowout jet [63,239] (figure 9b).…”

“…Finally, the reconnection in the internal current sheet further results in the full eruption of the mini-filament and the formation of the broad bubble-like CME, during which the erupting filament material forms the jet's cool component. Recently, more and more observations have evidenced the appearance of paired narrow and broad CMEs in association with on-disc blowout jets [155,239,243,253,254], and the phenomenological model of Shen et al [63] provides a possible explanation for these observations; however, further observational and numerical investigation is required to confirm this scenario.…”

Responses and Periodic Variations of Cosmic Ray Intensity and Solar Wind Speed to Sunspot Numbers

“…It is well known that various of solar activities are closely associated with solar magnetic field processes and the study of the long-term evolution of solar activities are useful for the understanding of the solar atmosphere and the dynamo theories (e.g., [1][2][3][4]). e sunspot numbers (SSN), being the most important index of the solar activities, have been widely studied together with other indices [5][6][7][8][9][10][11][12][13].…”
