Colloquia & Seminars

In the IWF colloquium and seminar series, international guest speakers (colloquium) and local speakers (seminar) inform about current research topics and scientific results every Thursday at 2 pm. The summer months are lecture-free.

Older lectures can be found on the IWF YouTube channel.

Colloquium: Chemical composition of Galactic stars in 3D NLTE

Dr. Maria Bergemann (research group leader, MPIA Heidelberg, Germany) will show us how 3D radiation hydrodynamical modeling of stellar atmospheres, including non-LTE effects, has advanced our ability to precisely determine element abundances and conclude about the chemical evolution of the Milky Way.

Seminar: Confirming and characterizing small transiting planets with ESPRESSO

How to identify small exoplanets? Dr. Melissa Hobson (Geneva Observatory) gives an overview of 43 planets (from super-Mercuries to Mini-Neptunes) confirmed with the ESPRESSO spectrograph at the Very Large Telescope in Chile as the premier instrument to characterize small exoplanets.
