Description

We are pleased to announce our international workshop on “Origin of Elements and Cosmic Evolution” (OECE2025), NOV 10-14, 2025 in Beihang University, China. 

Nuclear astrophysics and cosmology is a rapidly advancing field at the intersection of nuclear physics, astrophysics, and cosmology. It seeks to understand the origin of the elements, the evolution of stars and galaxies, and the fundamental processes that have shaped the universe from the Big Bang to the present day. Recent progress in observations, experiments, and theoretical modeling—such as high-resolution spectroscopy, gravitational wave detection, and large-scale simulations—has opened up new opportunities to explore nucleosynthesis, stellar explosions, and the cosmic chemical evolution in unprecedented detail. As a truly interdisciplinary endeavor, this field plays a vital role in connecting the microscopic world of atomic nuclei with the macroscopic structure and history of the universe.

Pre-Workshop School

This year, the workshop will commence with a THREE-DAY SCHOOL specifically designed for international students and early-career researchers. The school aims to provide a comprehensive overview of the major advances in nuclear astrophysics and cosmology over the past decades, as well as to introduce the latest frontiers in the field. A number of distinguished international experts will be invited to deliver lectures and share their cutting-edge research.

Topics

The following topics are discussed in the workshop:

  • High-resolution spectroscopy and stellar abundances
  • Galactic archaeology and chemical evolution
  • Stellar evolution, supernovae, and compact objects
  • Heavy element nucleosynthesis (r-, i-, s-, and p-processes)
  • Nuclear physics & Nuclear reactions for astrophysics
  • Neutrinos and weak interactions in astrophysics

Registeration Information

Both participant registration and the call for abstracts will begin in late August. The total registration fee for both School and Workshop is now 1,000 RMB (cash only). The full timetable of the school and the list of invited lecturers will be released in future announcements.
