New Statistical Topology Theory Predicts Turbulent Magnetic Emergence from the Sun's Interior

Anda Xiong, Hongyan Li, Shangbin Yang +6

We propose and verify a new statistical topology framework to study the complex magnetic field evolution of Sun-like stars. The Sun, as the star we are most familiar with, exhibits…

Distribution of magnetic helicity and energy with height in solar atmosphere

Hongyan Li, Shangbin Yang, Haiqing Xu +3

Magnetic helicity and magnetic energy are key to understanding the solar dynamo and eruptions, and their three-dimensional distributions are of great significance. However, how the…

Estimation of gravitational wave from solar emerging magnetic flux tube

Siqi Guan, Shangbin Yang, Xiao Guo

This study investigates the gravitational waves (GWs) generated by the emergence of magnetic flux tubes in the solar convection zone. We focus on the upward buoyancy of magnetic fl…

Helicity Fluxes and Hemispheric Helicity Rule of Active Regions Emerging from the Convection Zone Dynamo

V. V. Pipin, Shangbin Yang, A. G. Kosovichev

Using a 3D non-linear mean-field solar dynamo model, we investigate the magnetic helicity flux and magnetic twist, and tilt parameters of bipolar magnetic regions (BMRs) emerging f…

Magnetic helicity evolution during active region emergence and subsequent flare productivity

Zheng Sun, Ting Li, Quan Wang +3

Aims. Solar active regions (ARs), which are formed by flux emergence, serve as the primary sources of solar eruptions. However, the specific physical mechanism that governs the eme…

An Automatic Approach for Grouping Sunspots and Calculating Relative Sunspot Number on SDO/HMI Continuum Images

Cui Zhao, Shangbin Yang, Tingmei Wang +4

Relative Sunspot Number is one of the major parameters for the study of long-term solar activity. The automatic calculation of the Relative Sunspot Number is more stable and accura…
