How are the abnormally hot chromosphere and corona heated by the solar magnetic fields?
K. J. Li, J. C. Xu, W. F eng +3
The corona is a structure possessed by stars, including the sun. The abnormal heating of the solar corona and chromosphere is one of the greatest mysteries in modern astronomy. Whi…
The role and contribution of magnetic fields, characterized via their magnetic flux, to the statistical structuring of the solar atmosphere
K. J. Li, J. C. Xu, W. Feng
The anomalous heating of the solar upper atmosphere is one of the eight key problems in modern astronomy. Moreover, the stratification of the solar atmosphere is an outstanding key…
Differential rotation of the chromosphere in the He I absorption line
KJ Li, JC Xu, JL Xie +1
Differential rotation is the basis of the solar dynamo theory. Synoptic maps of He I intensity from Carrington rotations 2032 to 2135 are utilized to investigate the differential r…
Characteristics of solar wind rotation
Kejun Li, W. Feng
Over 54 years of hourly mean value of solar wind velocity from 27 Nov. 1963 to 31 Dec. 2017 are used to investigate characteristics of the rotation period of solar wind through aut…
Why Does the Solar Corona Abnormally Rotate Faster Than the Photosphere?
KJ Li, JC Xu, ZQ Yin +1
Coronal heating is a big question for modern astronomy. Daily measurement of 985 solar spectral irradiances (SSIs) at the spectral intervals 1-39 nm and 116-2416 nm during March 1…
Is It Small-scale Weak Magnetic Activity That Effectively Heats the Upper Solar Atmosphere?
K. J. Li, J. C. Xu, W. Feng
Solar chromosphere and coronal heating is a big question for astrophysics. Daily measurement of 985 solar spectral irradiances (SSIs) at the spectral intervals 1-39 nm and 116-2416…
Solar-cycle related variation of solar differential rotation
K. J. Li, X. J. Shi, J. L. Xie +4
Solar-cycle related variation of differential rotation is investigated through analyzing the rotation rates of magnetic fields, distributed along latitudes and varying with time at…
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…
Why isn't the solar constant a constant?
K. J. Li, W. Feng, J. C. Xu +4
In order to probe the mechanism of variations of the Solar Constant on the inter-solar-cycle scale, total solar irradiance (TSI, the so-called Solar Constant) in the time interval…
The Phase Shifts of the Paired Wings of Butterfly Diagrams
Kejun Li, Hongfei Liang, Wen Feng
Sunspot groups observed by Royal Greenwich Observatory/US Air Force/NOAA from May 1874 to November 2008 and the Carte Synoptique solar filaments from March 1919 to December 1989 ar…
