Understanding the massive-star origin of our elements: A unified understanding of stellar yields

Hengstberger-Symposium - Heidelberg, 4-8 September 2023

The symposium will consist of presentations with ample time for discussion between and during the talks. While the presentation times will thus be very flexible and can be adjusted during the meeting, the following program scheme including the starting time and spancenters are fixed for organizational purposes:
