Planetary Impacts and Physics of Planetary Interiors Ahrens Symposium

这个奖项将帮助支持一个以行星撞击和行星内部物理为重点的研讨会。这次研讨会是为了纪念Tom Ahrens教授从加州理工学院退休，以及他在矿物物理领域做出的许多和各种贡献而举办的。阿伦斯教授和他在林德赫斯特实验地球物理实验室的学生和同事一直在积极研究地球和行星内部矿物的高压性质，以及对行星表面的影响，如产生陨石坑、行星的吸积和原始大气覆盖的岩浆海洋的形成。阿伦斯的团队率先使用一系列波长的光辐射与时间的关系来直接确定冲击波的温度。最近在地幔下部发现的后钙钛矿相在矿物物理学和地震界引起了很大的兴奋，这次研讨会应该会带来许多活跃和有趣的讨论。研讨会的计划反映了Ahrens教授广泛的研究兴趣，从地球和行星的起源、分化和演化，到实验室和航天器对行星材料物理性质的测量，再到对行星表面和大气的影响过程。研讨会上有初级和高级演讲者，包括阿伦斯教授最近的一些学生和博士后。

The symposium is organized in honor and recognition of Prof. Tom Ahrens' retirement from Caltech and his many and varied contributions to the field of mineral physics. Prof. Ahrens, with his students and colleagues in the Lindhurst Laboratory of Experimental Geophysics, has been actively conducting research on the high-pressure properties of minerals of the Earth and planetary interiors, as well as impact effects on planetary surfaces, such as production of craters, accretion of the planets, and formation of magma oceans overlain by primitive atmospheres. Ahrens' group has pioneered the use of optical radiation versus time at a series of wavelengths to directly determine shock temperatures. The recent detection of the postperovskite phase in the lowermost mantle has generated a lot of excitement within the mineral physics and the seismological communities, and the symposium should bring about much lively and interesting discussion. The program for the symposium reflects Prof. Ahrens' broad research interests ranging from the origin, differentiation and evolution of the Earth and planets to laboratory and spacecraft-based measurements of the physical properties of planetary materials to impact processes on planetary surfaces and atmospheres. The symposium features a balance of junior and senior speakers, including some of Prof Ahrens' most recent students and postdocs.
