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.

Travel Information
By train:

You can check available connections with Deutsche BahnExternal link (English version). For details on specific connections from the airports, see below. It is advisable to make a seat reservation if you travel with an ICE.

By train from different airports (Frankfurt, Munich, Berlin):

The trains (ICE) from Frankfurt go frequently and take about three and a half hours. The official name of the station for departure is Frankfurt(M) Flughafen Fernbf. There is no direct train to Jena. You have to change to a regional train in Erfurt. You arrive at the station Jena-West. There is again no direct connection between the Airports in Munich or Berlin and Jena. However, ICEs from Munich to Jena and Berlin to Jena run every hour. You have to change in Erfurt or Naumburg to regional trains. You arrive at the station Jena-West or Jena-Paradise, respectively.
