Sunspot: the latest simulation

For a long time, the principle of internal activity of sunspots on the sun has always been a mystery, but today we can use computers to simulate its activity and observe more clearly.

Understanding the complex dynamics principle generated in sunspots helps scientists become more aware, and can predict how the magnetic field generated from sunspots affects the system. news and climate.

Matthias Rempel, a helper for computer modeling research at the US National Research Center NCAR, said: 'This is the first time we have described the complete sunspot model. If you want to understand the working mechanism of the earth, you must first understand the process of forming and developing sunspots. '

Sunspot is a very strong area of ​​magnetic activity on the surface of the sun. Because the temperature of the black spot is very low, compared to the ambient temperature of 10,000 degrees Fahrenheit, it only has a temperature of about 7,000 degrees Fahrenheit, so it looks darker than the surrounding environment.

In the magnetic field of the sunspot, we can observe a large amount of light and extrusion from the sun. These substances will fall into the earth's space, hindering electronic networks, satellites and other systems.

The active cycle of extremes of the sun is 11 years, this is the period when it is most active, then gradually disappears. Currently, sunspot activity is quite short, so the sun and sunspot activity are quite small .

This is the latest simulation for the sun area with a surface radius of 49879m x 99758m, a depth of 5953m. Simulation images on the computer that detect sunspot have two opposite electrodes. This detailed model shows that the central black area is the central black part of the sunspot, so the dark half around the sunspot has a lot of filaments.

This simulation shows that the magnetic field in the sunspot must be tilted in a certain direction to produce this phenomenon. Matthias Rempel and his colleagues say that, based on the characteristic of sunspots, we can explain convection in a magnetic field.

Michael Konofaike (NCAR Center) said: Scientists have experimented with this groundbreaking simulation to complete the physical diagram, which can set the surface observations, formation, dynamics and melting. Turning of sunspot links together. The high-end Blue file computers of NCAR National Research Center were used to perform simulation experiments, and ground and space telescopes were also used for observation.

The results of this study are published in the June 19, 2009 Journal of Science . The US National Science Foundation is the organization that sponsors this research project.
