Star cluster research is experiencing a very exciting decade. With the Atacama Large Millimeter / submillimeter Array and the Gaia astrometric satellite, we are now equipped to probe the full lifecycle of star clusters, from the properties of the molecular gas in which they form, to the properties of the stellar streams which dying clusters leave in their wake. To exploit fully and meaningfully these huge data flows, the active collaboration of observers and modellers is critically needed. What theoretical predictions are we able to make? What are the observable quantities? How well do we understand observational data?
Moreover, the time is ripe for a hard look at the physical conditions leading to the formation of clusters in the Galaxy and the Magellanic Clouds, and their imprint on the long term evolution of clusters.
Our aim is therefore also to bring together experts working on the formation of the cluster gaseous precursors with those studying the latest stages of cluster dissolution.
Particular attention will be given to the first Gyr of cluster evolution, that is, the infancy and teenagehood of clusters. This is over that age range that most clusters in the Galactic disc dissolve and, therefore, the age range over which a good understanding of cluster mass-loss mechanisms is most critically needed. Moreover, this is by that cluster age that the intriguing multiple stellar populations of globular clusters have formed. A related question is thus whether their formation can be witnessed directly in massive clusters currently in their teenagehood, or whether a key role was played by the different environmental conditions at the time of their formation.

Bus 31 from Bismarckplatz and Universitätsplatz
Busses 32 and 24 from the Main Train Station; also bus 21 but not later than ca. 18:15
- After getting off, follow Berliner- or Humboldt Strasse
- Please note: lines 21 and 24 are normally tram-lines. Owing to a building site, however, trams 21 and 24 are, from the Main Train Station, towards the conference venue, substituted with busses (`Ersatzverkehr').
If the weather is fine, walking from the Main Train Station or Bismarckplatz is also a possibility

Traveling to and Staying in Heidelberg
From Frankfurt Airport (FRA) to Heidelberg (ca. 90km), you have the following options:
From Stuttgart Airport (STR) to Heidelberg:
- Take the S-Bahn from the airport to Stuttgart Hauptbahnhof (ca. 25 minutes ride). Continue by
train to "Heidelberg Hbf" (see To Heidelberg by train)
Participants to the conference can use one of the following options:
- A number of rooms have been booked at a preferential rate in several hotels in Heidelberg, 7 - 13 August 2016. You can book one of those by following this link of Heidelberg Marketing GmbH. Additional instructions about how to proceed can be found here (pdf file).
We wish you a pleasant stay in Heidelberg!
- Should you wish to find cheaper prices, you may consider:
Note that for these three hotels, no block booking has been made and, therefore, no special rate applies.
