From May 6 to 10, 2019, the second China-Europe Solar Physics Meeting (CESPM2019) was held in Hvar, Croatia. The conference was co-sponsored by solar physicists from China and Europe to promote exchanges and deepen cooperation. The conference has set up five special topics covering the international frontier research fields such as solar atmospheric heating, wave, magnetic reconnection, flare and CME, and solar wind.
It is reported that more than 200 Chinese and European scholars participated in the conference, and more than 140 posters were received. Six outstanding student posters were selected. Among the many posters, the poster of Guo Mingzhe, a postgraduate student of our school, stood out as one of the three Chinese student posters, winning the Outstanding Student Poster Award. Guo Mingzhe was a master student of our school in 2014. During his master career, he won the 2015 National Master Scholarship and the Outstanding Academic Achievement Award of Shandong University. He was awarded the 2015 Outstanding master's degree Student of Shandong University. Then he entered the PHD study in September 2016. Now under the joint guidance of Dr. Li Bo and Dr. Tom Van Doorsselaere from the University of Leuven Belgium, he has conducted numerical simulation studies of solar atmospheric fluctuations and heating. At this meeting, Guo Mingzhe introduced the latest research work to the participants through the poster, and actively exchanged discussions with domestic and European counterparts
Recent years, more and more observational studies have found that fluctuations are ubiquitous in the magnetic structure of the solar atmosphere, and are often accompanied by the attenuation of wave energy, thus reviving the traditional exchange type sundial heating mechanism. Guo Mingzhe's recent research work is based on the research of the Coronal ring. Based on the observation that the ring-foot drive source contains multiple rather than single-mode disturbances, the full three-dimensional numerical simulation is the main method, and different introductions are made in the ankle ring foot. The type of drive explores the establishment of wavefields in the ankle ring, the development of small-scale structures, and the subsequent dissipation of disturbances. In particular, this series of studies has shown that due to the lateral non-uniformity of the enthalpy ring medium, the small-scale vortex caused by the mixing of the twisted Alfven waves plays a catalytic role in the dissipation of the twisted mode.. As part of the research in this series, Guo Mingzhe has published two papers in the top journal of the Astrophysical Journal, as the first author and Shandong University being the first affiliation (one of them is being reviewed).Besides, he has published a collaborative paper in Astronomy and Astrophysics.
