Outline of Final Research Achievements

Why is the solar corona heated up to 100 million K ? Why does the solar wind (plasma flows from the Sun) exist? To answer the 2 questions and to predict the plasma flows from the stars, we conducted numerical simulations. Then we succeeded to reproduce both the solar corona and the solar wind in super computers.According to the results, we found that the solar atmosphere is heated by shocks and turbulence and that the resultant pressure gradient force drives the plasma flows.From this study, we could make the building blocks to predict stellar winds where the similar heating mechanisms would exist.
