The talk will be given in Chinese.
Title: The Origin and Evolution of the Elements: A Modern Perspective

Abstract:
I will review the processes of making the elements in various astrophysical environments, emphasizing the role of fundamental physics and observational evidence. I then discuss how to understand chemical evolution from both the ab initio and the data-driven approaches, contrasting the respective central issues. To illustrate the latter approach, I show how the average production patterns of Fe, Sr, Ba, and Eu by core-collapse supernovae and neutron star mergers can be inferred from the data on metal-poor stars in the Galactic halo.

Bio: 

Professor Yong-Zhong Qian (钱永忠) received his Bachelor of Science in Physics from the University of Science and Technology of China in 1989, and his PhD in Physics from the University of California, San Diego in 1993. He was a research associate at the National Institute for Nuclear Theory, University of Washington, Seattle from 1993 to 1995, the David W. Morriroe Fellow in Theoretical Physics at the California Institute of Technology from 1995 to 1998, and the J. Robert Oppenheimer Fellow at the Los Alamos National Laboratory from 1998 to 1999, before he joined the faculty at the University of Minnesota. He was elected Fellow of the American Physical Society in 2008 for contributions to theoretical nuclear astrophysics, including the production of heavy elements via the rapid neutron capture process and to theoretical studies of collective neutrino flavor transformations in supernovae.
