摘要
近年,随着兆焦耳级激光器装置的发展人们可以在实验室中创造出与极端天体环境类似的物理条件,这使科学家有机会对某些重要天体物理过程或物理现象在实验室中进行研究。简单介绍由美国国家点火装置驱动高能量密度实验室天体物理方面实验的若干进展,包括超新星遗迹中的瑞利-泰勒不稳定性、激光惯性约束聚变探测恒星核心环境下的热核反应、无碰撞冲击波、行星内部状态研究、恒星形成研究等,这将为我国在建的神光Ⅳ激光装置开展实验室天体物理方面的科学实验提供借鉴。最后对将来利用神光Ⅳ可能开展的实验室天体物理学方向相关的科学问题研究进行简单的展望。
In recent years, with the development of Mega-joule class Laser, creating physical conditions similar to those of extreme celestial environments in the laboratory became possible. This provides a way to do laboratory studies of some important astrophysical processes and physical phenomena. This paper briefly introduces several advances in the high energy density laboratory astrophysics which is driven by the national ignition facility(NIF). They includ the Rayleigh Taylor instability in the real supernova relic, the collisionless shock wave,laser inertial confinement fusion detecting the thermonuclear reaction under the condition of stellar nucleus, the study of the inner state of the planet and star formation. A reference is provided for the under construction Shenguang Ⅳ laser facility in China to carry out scientific experiments in the field of astrophysics in the laboratory. Finally, the scientific issues related to the direction of laboratory astrophysics using Shenguang Ⅳ laser facility in the future are briefly discussed.
