Diagnostic of Spectral Lines in Magnetized Solar Atmosphere: Formation of the H\b{eta} Line in Sunspots
Hongqi Zhang
Formation of the H 4861.34 Å line is an important topic related to the diagnosis of the basic configuration of magnetic fields in the solar and stellar chromospheres. Specifi…
Multi-wavelength Observation of a Failed Eruption from a Helical Kink-unstable Prominence
Haiqing Xu, Jiangtao Su, Jie Chen +7
Multi-wavelength observations of prominence eruptions provide an opportunity to uncover the physical mechanism of the triggering and the evolution process of the eruption. In this…
The origin and effect of hemispheric helicity imbalance in solar dynamo
S. Yang, V. V. Pipin, D. D. Sokoloff +2
In this paper we study the effects of hemispheric imbalance of magnetic helicity density on breaking the equatorial reflection symmetry of the dynamo generated large-scale magnetic…
From Polarimetry to Helicity: Studies of Solar Magnetic Fields at the Huairou Solar Observing Station
Hongqi Zhang
In this paper, we briefly introduce the basic questions in the measurements of solar magnetic fields and the possible error sources due to the approximation of the theory of radiat…
Improvements of the Longitudinal Magnetic Field Measurement from the Solar Magnetic Field Telescope at Huairou Solar Observing Station
Andrei Plotnikov, Alexander Kutsenko, Shanbin Yang +4
The weak-field approximation implying linear relationship between Stokes and longitudinal magnetic field, , often suffers from saturation observed in strong magnet…
Solar Kinetic Energy and Cross Helicity Spectra
Hongqi Zhang, Axel Brandenburg
We develop a formalism that treats the calculation of solar kinetic energy and cross helicity spectra in an equal manner to that of magnetic energy and helicity spectra. The magnet…
