Decayless longitudinal oscillations of a solar filament maintained by quasi-periodic jets
Y. W. Ni, J. H. Guo, Q. M. Zhang +3
Context: As a ubiquitous phenomenon, large-amplitude longitudinal filament oscillations usually decay in 1--4 periods. Recently, we observed a decayless case of such oscillations i…
Explosive Chromospheric Evaporation in a Circular-ribbon Flare
Q. M. Zhang, D. Li, Z. J. Ning +3
In this paper, we report our multiwavelength observations of the C4.2 circular-ribbon flare in active region (AR) 12434 on 2015 October 16. The short-lived flare was associated wit…
Blobs in recurring EUV jets
Q. M. Zhang, H. S. Ji
In this paper, we report our discovery of blobs in the recurrent and homologous jets that occurred at the western edge of NOAA active region 11259 on 2011 July 22. The jets were ob…
A swirling flare-related EUV jet
Q. M. Zhang, H. S. Ji
{We report our observations of a swirling flare-related EUV jet on 2011 October 15.} {We utilised the EUV observations from SDO/AIA. We extracted a wide slit along the jet axis and…
Chromospheric evaporation in sympathetic coronal bright points
Q. M. Zhang, H. S. Ji
{Chromospheric evaporation is a key process in solar flares that has extensively been investigated using the spectroscopic observations. However, direct soft X-ray (SXR) imaging of…
Parametric survey of longitudinal prominence oscillation simulations
Q. M. Zhang, P. F. Chen, C. Xia +2
It is found that both microflare-sized impulsive heating at one leg of the loop and a suddenly imposed velocity perturbation can propel the prominence to oscillate along the magnet…
