The Laboratory Astrophysics Workshop will focus on laboratory studies of
physical and chemical processes relevant to interstellar and
circumstellar media and planetary atmospheres. The scientific topics of the
workshop include (i) the formation, stability, structure, and spectral
properties of complex organic molecules, molecular clusters, molecular
ices, and dust grains, (ii) the origin of life on Earth,
and (iii) the physical and chemical properties of exoplanetary atmospheres.

The workshop will start on Monday, 22nd  November, at 9:00 am and close on Wednesday, 24th November 2021, at about 2:00 pm. Apart from invited talks, there will be a number of contributed talks and a poster session on Tuesday afternoon.

The program of the workshop, the book of abstract, and a list of all partcipants are now available.

On Monday evening, the 22nd November, we plan to have dinner for all participants in the Restaurant Bauersfeld (Am Planetarium 5) in the center of Jena.

On Wednesday, the 24th of November, we can offer a visit of our laboratory in Jena for interested participants.


Registration is closed.


The workshop will be held in the Old Castle of the three Dornburger Palaces, which are located high above the Saale Valley.

Dornburger Castles

07774 Dornburg-Camburg, Max-Krehan-Straße 4

The transport between Jena and Dornburg will be realized by bus transfer (WEIMAR-TOUR). The bus starts at 8:15 h at the bus station in front of the Paradise Train Station (Paradiesbahnhof). In the evening, the bus stops at the bus parking place in the Bibliotheksweg, which is in a one minute walking distance to the Restaurant Bauersfeld and 5 minutes to the hotels. On the last day, the bus will directly go to the Paradise Train Station (Paradiesbahnhof). Here, you can find the map of the center and a simplified map with the bus departure and arrival. Participants, who come with their own cars can park on a parking place very close to the castle. There are no parking fees.


There is no hotel in the village Dornburg. We will organize a daily transfer from Jena to Dornburg by bus. We have made block reservations for single and double rooms from 21.11. to 24.11.2021 in three different hotels. All of them are located in the center of the city.
