WE-Heraeus-Seminar "Chemical Evolution of Cosmic Matter"


The Seminar is motivated by the advent of new telescope facilities operating in the microwave and infrared region and featuring ultrahigh angular resolution and breathtaking sensitivity. This opens up new insights into processes leading to the formation and evolution of molecules in stellar environments that are otherwise inaccessible.

Invited Speakers


The program will be announced four months prior to the conference.
