It is shown that some of these relationships are satisfied to simple power laws. Fractal examination showed that some of these power laws can not be justified inside the simple models of stationary magnetic flux tube aggregation. All magnetic fluxes and corresponding areas were calculated using the data measured with the Solar Magnetic Field Telescope of the Huairou Solar Observing Station in Beijing.展开更多

The total intensity (I) VLBI image of the source shows a core-jet structure. The jet bends eastward at - 3 mas south of the core. Four components have been detected from results of fitting, with apparent speeds estimated at 6.7 ±0.7, 2.5 ±0.3, 4.5 ±0.5 h-1c for three jet components (taking H0 = 100 h km s-1 Mpc-1, q0 = 0.5). The polarization (P) VLBI image of 1611+343 displays the polarized configuration in the jet. The mechanism of the curved jet is discussed.展开更多

文摘We present a study of the relationship between integral area and corresponding total magnetic flux for solar active regions. It is shown that some of these relationships are satisfied to simple power laws. Fractal examination showed that some of these power laws can not be justified inside the simple models of stationary magnetic flux tube aggregation.
