 报告摘要:

  Significant progresses have recently been made for exploring astrophysical phenomena in laboratory with lasers. Rich in exciting physics, such undertakings provide tremendous but challenging opportunities for frontier science, advancing our understanding of various aspects fundamental to the structure and evolution of the universe. Interesting and important issues include, for example,

What controls the temperature and dynamics in stellar interiors? 

What are the interior structures of planets and how are they formed? 

How do massive stars explode as core-collapse supernovae? 

What are the conditions near an accreting black hole? 

How do gamma ray burst shocks form and radiate?

    While astrophysical phenomena have traditionally been studied with observations and theoretical modeling, the advent of high-intensity, high-energy lasers made it possible of a more quantitative approach in laboratories for validating and complementing such studies. In this talk, astrophysical phenomena at extreme conditions and their relationship with high-energy-density (HED) plasmas created by lasers are outlined. The physics and methodology for connecting laboratory experiments to astrophysical phenomena will be discussed. A number of recent experiments, including our work, for addressing the important issues in the frontier astrophysics will be introduced. These experiments have advanced our understanding of and provided important insight into many interesting astrophysical phenomena, including magnetic reconnection, plasma Instabilities and spontaneous fields, astrophysical jets and collisionless shocks, plasma nuclear science, equation of state, opacity, and pair electrons, etc. The highlights of these works have been manifested by numerous recent publications.
