Is there a Dynamic Difference between Stealthy and Standard CMEs?
Beili Ying, Alessandro Bemporad, Li Feng +2
Stealthy Coronal Mass Ejections (CMEs), lacking low coronal signatures, may result in significant geomagnetic storms. However, the mechanism of stealthy CMEs is still highly debate…
Plasma heating and nanoflare caused by slow-mode wave in a coronal loop
Fanxiaoyu Xia, Tongjiang Wang, Yang Su +4
We present a detailed analysis of a reflecting intensity perturbation in a large coronal loop that appeared as sloshing oscillation and lasted for at least one and a half periods.…
The Lyman- Emission in a C1.4 Solar Flare Observed by the Extreme Ultraviolet Imager aboard Solar Orbiter
Ying Li, Qiao Li, De-Chao Song +7
The hydrogen Lyman- (H {\sc i} Ly) emission during solar flares has rarely been studied in spatially resolved images and its physical origin has not been fully understood. In…
Spatially Resolved Moving Radio Burst in Association with an EUV Wave
Lei Lu, Li Feng, Weiqun Gan
Coronal mass ejections (CMEs) are large clouds of magnetized plasma ejected from the Sun, and are often associated with acceleration of electrons that can result in radio emission…
Three-dimensional analyses of an aspherical coronal mass ejection and its driven shock
Beili Ying, Li Feng, Bernd Inhester +4
Context. Observations reveal that shocks can be driven by fast coronal mass ejections (CMEs) and play essential roles in particle accelerations. A critical ratio, , derived from…
Observational Signatures of Tearing Instability in the Current Sheet of a Solar Flare
Lei Lu, Li Feng, Alexander Warmuth +7
Magnetic reconnection is a fundamental physical process converting magnetic energy into not only plasma energy but also particle energy in various astrophysical phenomena. In this…
Quasi-Periodic Pulsations Detected in Ly and Nonthermal Emissions During Solar Flares
Lei Lu, Dong Li, Zongjun Ning +2
We report quasi-periodic pulsations (QPPs) with double periods during three solar flares (viz. SOL2011-Feb-15T01:44, SOL2011-Sep-25T04:31, SOL2012-May-17T01:25). The flare QPPs wer…
Detection of flare multi-periodic pulsations in mid-ultraviolet Balmer continuum, Ly-alpha, hard X-ray, and radio emissions simultaneously
Dong Li, Mingyu Ge, Marie Dominique +7
Quasi-periodic pulsations (QPPs), which usually appear as temporal pulsations of the total flux, are frequently detected in the light curves of solar/stellar flares. In this study,…
Three-Dimensional Reconstructions of Coronal Wave Surfaces Using a New Mask-Fitting Method
Li Feng, Lei Lu, Bernd Inhester +5
Coronal waves are large-scale disturbances often driven by coronal mass ejections (CMEs). We investigate a spectacular wave event on 7 March 2012, which is associated with an X5.4…
Extensive Study of a Coronal Mass Ejection with UV and WL coronagraphs: the need for multi-wavelength observations
Beili Ying, Alessandro Bemporad, Li Feng +3
Coronal Mass Ejections (CMEs) often show different features in different band-passes. By combining data in white-light (WL) and ultraviolet (UV) bands, we have applied different te…
Quasi-periodic pulsation detected in Lyman-alpha emission during solar flares
Dong Li, Lei Lu, Zongjun Ning +3
We investigated the quasi-periodic pulsation (QPP) in Lyman-alpha, X-ray and extreme-ultraviolet (EUV) emissions during two solar flares, i.e., an X-class (SOL2012-01-27T) and a C-…
Relationships between Photospheric Vertical Electric Currents and Hard X-Ray Sources in Solar Flares: Statistical Study
I. V. Zimovets, I. N. Sharykin, W. Q. Gan
There are still debates whether particle acceleration in solar flares may occur due to interruption of electric currents flowing along magnetic loops. To contribute to this problem…
Spectroscopic and Stereoscopic Observations of the Solar Jets
Lei Lu, Li Feng, Ying Li +3
We present a comprehensive study of a series of recurrent jets that occurred at the periphery of the NOAA active region 12114 on 2014 July 7. These jets were found to share the sam…
A New Automatic Tool for CME Detection and Tracking with Machine Learning Techniques
Pengyu Wang, Yan Zhang, Li Feng +7
With the accumulation of big data of CME observations by coronagraphs, automatic detection and tracking of CMEs has proven to be crucial. The excellent performance of convolutional…
First Determination of 2D Speed Distribution within the Bodies of Coronal Mass Ejections with Cross-Correlation Analysis
Beili Ying, Alessandro Bemporad, Silvio Giordano +5
The determination of the speed of Coronal Mass Ejections (CMEs) is usually done by tracking brighter features (such as the CME front and core) in visible light coronagraphic images…
