Can the temperature of Ellerman Bombs be more than 10 000 K？被引量：2
《Research in Astronomy and Astrophysics》2017年第4期1-6,共6页Cheng Fang Qi Hao Ming-De Ding Zhen Li 
supported by the National Natural Science Foundation of China(NSFC,Grant Nos.11533005,11025314,13001003,11203014 and 11103075);NKBRSF(Grant 2014CB744203)
Ellerman bombs （EBs） are small brightening events in the solar lower atmosphere. By their original definition, the main characteristic of EBs is the two emission bumps in both wings of chro- mospheric lines, such a...

The continued debate on solar coronal EUV waves被引量：1
《Science China(Physics,Mechanics & Astronomy)》2017年第2期89-91,共3页PengFei Chen 
supported by the National Natural Science Foundation of China(Grant Nos.11533005,and 11025314);Jiangsu 333 Project
Gravity is everywhere in the universe[1,2],and the same is true of the magnetic field[3-5].Similar to gravity,magnetic field also controls the dynamics of the matter in the universe,over 99.9%of which is in the plasma...

Can we determine the filament chirality by the filament footpoint location or the barb-bearing？被引量：1
《Research in Astronomy and Astrophysics》2016年第1期1-12,共12页Qi Hao Yang Guo Cheng Fang Peng-Fei Chen Wen-Da Cao 
supported by NKBRSF (Grant Nos.2011CB811402 and 2014CB744203);the National Natural Science Foundation of China (Grant Nos.11203014,11533005 and 11025314);the grants from CSC201306190046 and CXZZ130041
We attempt to propose a method for automatically detecting the solar filament chirality and barb beating. We first introduce the concept of an unweighted undirected graph and adopt the Dijkstra shortest path algorithm...

Diagnostics of Ellerman bombs with high-resolution spectral data被引量：1
《Research in Astronomy and Astrophysics》2015年第9期1513-1524,共12页Zhen Li Cheng Fang Yang Guo Peng-Fei Chen Zhi Xu Wen-Da Cao 
supported by the National Natural Science Foundation of China (NSFC, Grants 10878002, 10933003, 11025314, 10673004, 11203014 and 11103075);NKBRSF (Grant Nos. 2011CB811402 and 2014CB744203);the support of the US NSF (AGS0847126 and AGS-1250818);NASA (NNX13AG14G)
Ellerman bombs （EBs） are tiny brightenings often observed near sunspots. The most impressive characteristic of EB spectra is the two emission bumps in both wings of the Hα and Ca II 8542 A lines. High-resolution sp...

Where do flare ribbons stop?被引量：2
《Chinese Science Bulletin》2012年第12期1393-1396,共4页CHEN PengFei SU JiangTao GUO Yan DENG YuanYong 
supported by the National Natural Science Foundation of China(11025314,10878002,and 10933003);the National Basic Research Program of China(2011CB811402);supported by an open research program of National Astronomical Observatories of China
The standard flare model,which was proposed based on observations and magnetohydrodynamic theory,can successfully explain many observational features of solar flares.However,this model is just a framework,with many de...

Hαcounterparts of X-ray bright points in the solar atmosphere
《Science China(Physics,Mechanics & Astronomy)》2012年第5期907-914,共8页ZHANG Ping FANG Cheng ZHANG QingMin 
supported by the National Basic Research Program of China (Grant No.2011CB811402);the National Natural Science Foundation of China (Grant Nos.10878002,10610099,10933003,10673004,10073005,10403003,and 11025314)
X-ray bright points （XBPs） are small-scale brightenings in the solar corona. Their counterparts in the lower atmosphere, how- ever, are poorly investigated. In this paper, we study the counterparts of XBPs in the up...

The inversion of the real kinematic properties of coronal mass ejections by forward modeling被引量：3
《Research in Astronomy and Astrophysics》2011年第2期237-244,共8页You Wu 1 and Peng-Fei Chen 1,2 1 Department of Astronomy,Nanjing University,Nanjing 210093,China 2 Key Lab of Modern Astron.and Astrophys.,Ministry of Education,Nanjing 210093,China

Kinematic properties of coronal mass ejections （CMEs） suffer from projection effects,and it is expected that the real velocity should be larger and the real angular width should be smaller than the apparent values.S...
