报告摘要：The Sun, our star, is the most important object in the heavens for us. It sustains almost all the lives on the Earth and impact our daily life in many aspects. Also as our nearest star, the Sun offers us a unique opportunity to study stellar physics in action. A major solar eruption is the most violent energy release process that occurs in the solar system. It usually sends more than 1032 ergs of energy and jets more than 1016 grams of mass into interplanetary space. Some of this mass in the form of energetic particles with energy in the range of 10 keV to 10 GeV can seriously damage satellites, disrupt ground communications and power grids, and wreak havoc on a world that has come to depend of satellites, electrical power, and radio communications. Thus studying solar eruptions and understanding the physics behind them are of broad scientific and socio-economical significance.
In this presentation, I shall discuss the sciences that the solar physicists focus on, the approaches to learning the physics behind observations, and the possible application of the results to forecasting the activities in the space environment around the Earth, namely the space weather, and to other fields of astrophysics.
