Two types of dynamic cool coronal structures observed with STEREO and Hinode
《Research in Astronomy and Astrophysics》2009年第12期1368-1376,共9页Jun Zhang Le-Ping Li 
supported by the National Natural Science Foundation of China(Grant Nos.40890161 and 40674081);the CAS Project KJCX2-YW-T04,and the National Basic Research Program of China(Grant No.G2006CB806303)
Solar coronal loops show significant plasma motions during their formation and eruption stages. Dynamic cool coronal structures, on the other hand, are often observed to propagate along coronal loops. We report on the...

Chromospheric oscillations observed with BBSO and TRACE被引量：2
《Science China(Physics,Mechanics & Astronomy)》2009年第11期1718-1722,共5页SONG Qiao ZHANG Jun 
Supported by the National Natural Science Foundation of China (Grant Nos. G10873020, 10603008, 40890161, 10703020, 40674081, and10703007);the CAS Project (Grant No. KJCX2-YW-T04);the National Basic Research Program of China (Grant No. G2006CB806303)
We examine chromospheric oscillations in both a coronal hole (CH) and a quiet Sun (QS) region, by employing Transition Region and Coronal Explorer (TRACE) and Big Bear Solar Observatory (BBSO) data on September 14 and...

A statistical study on the brightening propagation of post-flare loops被引量：3
《Science China(Physics,Mechanics & Astronomy)》2009年第11期1723-1727,共5页LI LePing DUAN HongYu ZHANG Jun 
Supported by the National Natural Science Foundation of China (Grant Nos. G10703007, 40890161, 10603008, 40674081, and 10733020);the CAS Project (Grant No. KJCX2-YW-T04);the National Basic Research Program of China (Grant No. G2006CB806303)
After examining the data observed by TRACE 171 and 195  from May 1998 to December 2006, we choose as our sample 190 (39 X-class and 151 M-class) flare events which display post-flare loops (PFLs). We investigate the...

Magnetic non-potentiality on the quiet Sun and the filigree被引量：3
《Research in Astronomy and Astrophysics》2009年第8期933-944,共12页Meng Zhao Jing-Xiu Wang Chun-Lan Jin Gui-Ping Zhou 
supported by the National Natural Science Foundation of China (10873020, 10703007, G10573025, 40674081, 10603008, 10733020 and 40890161);the Chinese Academy of Sciences Project KJCX2-YW-T04;the National Basic Research Program of China(G2006CB806303)
From the observed vector magnetic fields by the Solar Optical Telescope/ Spectro-Polarimeter aboard the satellite Hinode, we have examined whether or not the quiet Sun magnetic fields are non-potential, and how the G-...

Interaction between granulation and small-scale magnetic flux observed by Hinode被引量：3
《Research in Astronomy and Astrophysics》2009年第8期921-932,共12页Jun Zhang Shu-Hong Yang Chun-Lan Jin 
supported by the National Natural Science Foundations of China (Nos. 10573025,40674081 and 40890161);the CAS Project KJCX2-YW-T04;the National Basic Research Program of China under grant G2006CB806303
With the polarimetric observations obtained by the Spectro-Polarimeter on board Hinode, we study the relationship between granular development and magnetic field evolution in the quiet Sun. Six typical cases are displ...

Flare-induced signals in polarization measurements during the X2.6 flare on 2005 January 15

Flare-induced signals in polarization measurements which were manifested as apparent polarity reversal in magnetograms have been reported since 1981. We are motivated to further quantify the phenomenon by asking two q...
