They have created a model that explains how exactly the plasma jets of the solar surface are formed. These plasma jets are called spicles. Every day thousands of spikelets emerge in which the plasma leaves the surface of the Sun towards the crown at a speed of 50-150 kilometers per second. A hundred years ago they were observed, but it was not very clear how they were created. Now they have created a model in which the simulations performed fully coincide with what happens in the Sun. In this way they have been able to determine the physical interactions that occur between the solar plasma and the magnetic field. And at the same time this explains how the outer atmosphere of the Sun reaches such a high temperature due to the spicles. The work has been published in the journal Science.
