The cosmic surroundings of the Earth – where are our astronauts and space ships – can be “shocked” giant solar eruptions, in which a giant cloud of magnetic energy and plasma, a hot gas comprised of electrically charged particles thrown out into space. Magnetic field, these solar eruptions are quite difficult to predict, and it can interact with magnetic fields of the Earth, causing our planet to space weather effects.
A new tool called EEGGL ( Eruptive Event Generator by Gibson and Low) helps to calculate the trajectory of the particles of these structured magnetic field of clouds, called coronal mass ejections (coronal mass ejections, CMEs), before they reach the Ground. EEGGL is part of a larger new model of the solar corona developed by the research team from the University of Michigan, USA.
This new model known as the model built on the basic principles because the calculations in it are based on fundamental physical theory describing a phenomenon – in this case, the description is based on properties of plasma and magnetic free energy that determine the movement of the CME through space.
Such computer models can help researchers better understand the Sun’s influence on near-earth space and to improve the accuracy of our forecasts of space weather.
