Helicity transport from solar convection zone to interplanetary space
Mei Zhang
Magnetic helicity is a physical quantity that describes field topology. It is also a conserved quantity as Berger in 1984 demonstrated that the total magnetic helicity is still con…
Multi-height observations of magnetoacoustic cut-off frequency in a sunspot atmosphere
Ding Yuan, R. Sych, V. E. Reznikova +1
We used the Pixelised Wavelet Filtering (PWF) method to compute narrow-band power maps of SDO/AIA imaging datasets in the 1700 Å, 1600 Å and 304 Å bandpasses that correspond to dif…
Venus transit, aureole and solar diameter
Wenbin Xie, Costantino Sigismondi, Xiaofan Wang +1
The possibility to measure the solar diameter using the transits of Mercury has been exploited to investigate the past three centuries of its evolution and to calibrate these measu…
Geometrical information on the solar shape: high precision results with SDO/HMI
Xiaofan Wang, Costantino Sigismondi
The uncertainty of measurement of solar diameter is depending on the observational time scale. Full-disc images of SDO/HMI and the images from ground observations in Huairou Solar…
SDO/AIA Observations of Large-Amplitude Longitudinal Oscillations in a Solar Filament
Ting Li, Jun Zhang
We present the first \emph{Solar Dynamics Observatory}/Atmospheric Imaging Assembly observations of the large-amplitude longitudinal (LAL) oscillations in the south and north parts…
Emerging dimmings of active regions observed by SDO
Jun Zhang, Shuhong Yang, Yang Liu +1
With the observations from the Atmospheric Imaging Assembly and the Helioseismic and Magnetic Imager aboard the \emph{Solar Dynamics Observatory}, we statistically investigate the…
Relaxation of magnetic field relative to plasma density revealed from microwave zebra patterns associated with solar flares
Sijie Yu, Yihua Yan, Baolin Tan
It is generally considered that the emission of microwave zebra pattern (ZP) structures requires high density and high temperatures, which is similar to the situation of the flarin…
The Morphologic Properties of Magnetic networks over the Solar Cycle 23
Chong Huang, Yihua Yan, Yin Zhang +2
The morphologic properties of the magnetic networks during Carrington Rotations (CR) 1955 to 2091 (from 1999 to 2010) have been analyzed by applying the watershed algorithm to magn…
Flares and Magnetic Non-potentiality of NOAA AR 11158
Qiao Song, Jun Zhang, Shuhong Yang +1
The magnetic non-potentiality is important for understanding flares and other solar activities in active regions (ARs). Five non-potential parameters, i.e., electric current, curre…
Microwave burst with fine spectral structures in a solar flare on 2011 August 9
Baolin Tan, Chengming Tan, Yuying Liu
On August 9, 2011, there was an X6.9 flare event occurred near the west limb of solar disk. From the observation obtained by the spectrometer of the Chinese Solar Broadband Radio S…
A Statistical Study on Force-Freeness of Solar Magnetic Fields in the Photosphere
S. Liu, J. T. Su, H. Q. Zhang +4
It is an indisputable fact that solar magnetic fields are force-free in the corona, where force free fields means that current and magnetic fields are parallel and there is no Lore…
Study of flare energy release using events with numerous type III-like bursts in microwaves
N. S. Meshalkina, A. T. Altyntsev, D. A. Zhdanov +4
The analysis of narrowband drifting of type III-like structures in radio bursts dynamic spectra allows to obtain unique information about primary energy release mechanisms in solar…
Magnetic Helicity of Self-Similar Axisymmetric Force-free Fields
Mei Zhang, Natasha Flyer, Boon Chye Low
In this paper we continue our theoretical studies on addressing what are the possible consequences of magnetic helicity accumulation in the solar corona. Our previous studies sugge…
Quantifying solar superactive regions with vector magnetic field observations
A. Q. Chen, J. X. Wang
The vector magnetic field characteristics of superactive regions (SARs) hold the key for understanding why SARs are extremely active and provide the guidance in space weather predi…
Self-cancellation of ephemeral regions in the quiet Sun
Shuhong Yang, Jun Zhang, Ting Li +1
With the observations from the Helioseismic and Magnetic Imager aboard the Solar Dynamics Observatory, we statistically investigate the ephemeral regions (ERs) in the quiet Sun. We…
Long-term Variations of Solar Differential Rotation and Sunspot Activity: Revisited
K. J. Li, W. Feng, X. J. Shi +3
Long-term variations of solar differential rotation and sunspot activity are investigated through re-analyzing the data on parameters of the differential rotation law obtained by M…
Surface flux evolution constraints for flux transport dynamos
R. H. Cameron, D. Schmitt, J. Jiang +1
The surface flux transport (SFT) model of solar magnetic fields involves empirically well-constrained velocity and magnetic fields. The basic evolution of the Sun's large-scale sur…
Magnetic helicity transported by flux emergence and shuffling motions in Solar Active Region NOAA 10930
Y. Zhang, R. Kitai, K. Takizawa
We present a new methodology which can determine magnetic helicity transport by the passage of helical magnetic field lines from sub-photosphere and the shuffling motions of foot-p…
