  简介:

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.

报告人简介:林隽研究员1985年毕业于南京大学天文系,获理学学士学位。1988年获得天体物理学硕士学位后到云南天文台太阳光谱组工作。1997年,进入美国新罕布什尔州立大学物理系攻读博士学位。2001年7月开始进入美国哈佛-史密松天体物理中心工作。2001年9月获得物理学博士学位。2005 年4月正式回国工作。现任云南天文台“太阳爆发与CME研究”团组首席研究员、博士生导师。主要研究领域包括理论太阳物理,太阳爆发(太阳耀斑、爆发日珥、日冕物质抛射)过程中的等离子体和磁场征、不稳定性、磁力线重联、解析模型。建立了日冕物质抛射/太阳耀斑的Lin-Forbes模型。
