Magnetic solar poles overturn with a cycle of 11 years, which is determined by the speed of rotation and brightness. A similar scenario is repeated in all nearby stars of the solar type.
It used to be thought that the Sun was a kind of anomaly with its 11-year cycle of magnetic poles. However, recent data show that this is a normal state for all stars of this type. This will help to resolve disputes over this issue.
Researchers are based on long-term observations and suggest that the next magnetic cycle in 10-20 years will be more intense, longer or shorter. It is very important to understand this moment, since you have to take into account these indicators to determine the launch window of the missiles.
The cycle is characterized by the number of sunspots and the power of the emission of rays. Any changes are based on the magnetic field. Scientists began to ask questions, because it seemed that the sun does not fit the stars like themselves in a cycle.
The longitudinal magnetic field acts as a function of latitude and time at the base of the convection zone. Periodically, it changes sign and oscillates between the symmetric and antisymmetric state
Researchers tracked the nearest solar stars, creating models of cyclic activity. The latest data confirm that the situation repeats on all objects of this group.
The ratio of the periods of the magnetic cycle and the rotation of the star, based on the number of Rossby in turbulent 3 D-simulations (left). On the right is the same ratio as a function of the stellar luminosity. The diagram includes the Sun and other similar types. Solar twins are highlighted in purple. Simulation (blue discs) cross the solar point without setting parameters. Vertical dotted lines - stars with two periods of a magnetic cycle
