207. Simulating the formation and eruption of magnetic flux ropes in the solar atmosphere

Contributed by P. Vemareddy. Posted on January 8, 2025

The coronal magnetic field evolution of the AR 11429 was simulated using time-dependent magneto-friction model. The model reproduced the magnetic structure that has remarkable correspondence with the spatial characteristics in coronal extreme ultraviolet images.

206. Magnetic power spectra of the Sun and cycle dependence of magnetic network

Contributed by Yukun Luo. Posted on January 7, 2025

Magnetic power spectra were calculated using MDI and HMI data for two solar cycles. It is found that the sizes of the magnetic networks do not show a cycle dependence, but the power-law indices estimated from the active region and network sizes show an anti-correlation with the sunspot numbers.
