Introduction
We are happy to announce a small workshop on "Debris discs: At Home and Abroad". The workshop will be held in Jena, Germany, from 29 August to 2 September 2022. Room capacities limit the attendance to about 50 participants.
The meeting is part of the series "Current and future trends in debris disc science". Following the spirit of the previous very stimulating meetings (Victoria 2018, Budapest 2019, virtual EAS 2021), the goal is to strengthen collaboration and discussion among scientists working on extrasolar and solar debris discs. Most importantly, this workshop is aimed at inspiring and intensifying the dialogue between researchers using various approaches – observations, theory, and laboratory studies. Students and postdocs are encouraged to present their results and to use the opportunity to learn more about the main questions and most recent results.
The workshop is neutral in terms of funding. This implies that no registration fee is charged and that no financial support is offered to the participants. In exceptional cases, the organisers will try to arrange some support from the funds provided to us by the German Research Foundation (DFG) for the meeting organization.

Travel information
General information:
No matter which point in Jena you will arrive at (the bus station 'ZOB', the train stations 'Jena West', 'Jena Paradies'), all the 'places of interest' (recommended hotels, institute = icebreaker place, conference venue) are within walking distance.
We recommend for you to use travel planning apps to help with your journey, e.g. Google maps, Rome2rio.
By long-distance bus:
Long-distance buses are typically one of the cheapest means of transport. However, they reach Jena only a few times a day. 'Flixbus' (English version) operates with connections to and from Jena. The central bus station (ZOB) is located close to the long-distance train station, 'Jena Paradies'. We recommend using the 'Flixbus' App. It tells you the exact arrival time of the bus.
By train:
Jena has two train stations in the city centre. 'Jena West', that serves East-West connections, and 'Jena Paradies', that serves North-South connections.
You can check available connections with 'Deutsche Bahn' (English version). For details on specific train connections from some airports, see below.
For those flying in to Germany, it's worth being aware that many airlines, e.g. Lufthansa, offer a 'Rail&Fly' ticket. This essentially gives you a flexible train ticket for the day following your arrival and the day preceding your departure and is much much cheaper than a Deutsche Bahn flexible ticket.
It is advisable to make a seat reservation if you travel with an express train (ICE, IC, EC), especially on Fridays and Sundays. You can find a scheme with the passenger cars' stopping positions (called 'Wagenstandanzeiger') at each platform. 'Deutsche Bahn' offers special cheaper tickets, e.g. for people who book very early (super saver fare) or early (saver fare). However, these tickets are valid only for one specific connection. Until end of August nearly all tickets for regional(!) passenger transport are much cheaper (9 € per month).
We strongly recommend using the 'DB Navigator' app of 'Deutsche Bahn'. It shows live expected arrival / departure times, platform numbers, suggested alternatives if one is delayed, etc. It stores a QR code of your ticket and is fully available in English.
HINT: 'Deutsche Bahn' is not necessarily punctual. We recommend changing the "Duration of transfer" (under "Stopover") at the DB website or in the app to at least 15 minutes.
By train from Frankfurt Airport (FRA):
FRA via Erfurt to Jena (every 2h, 1 change, ~3.5h travel time; arrival: 'Jena West')
The trains from Frankfurt depart at least every two hours and take about three and a half hours. The official name of the station for departure is 'Frankfurt(M) Flughafen Fernbf'. The train does not go directly to Jena. You have to change once: to a regional train in Erfurt. About half an hour later, you reach 'Jena West'.
By train from Munich Airport (MUC):
MUC via Erfurt to Jena (every hour, 2 changes, ~4.5h travel time, arrival: 'Jena West')
You first have to take the city train (S 8) to the central station 'München Hbf'. Then, you have to go from the underground platforms for city trains and trams to the platforms for long-distance trains. There, an ICE departs at least once an hour, reaching Erfurt about three hours later. There you have to change again: to a regional train. About half an hour later, you reach 'Jena West'.
By train from Berlin Airport (BER):
BER (Hbf/Südkreuz) via Erfurt or Halle(Saale) (at least 1x per hour, 2 changes, 3-3.5h travel time; arrival: 'Jena West'/ 'Jena Paradies')
You first have to take the city train or a regional train to the main train station 'Berlin Hbf' or sometimes to 'Berlin Südkreuz', 'Berlin Gesundbrunnen' or 'Treptower Park'. From there take an express train (IC or ICE) to either 'Halle (Saale)'- one hour - or to Erfurt - one and a half hours. You then have to change to a regional train. From Erfurt you reach 'Jena West' about half an hour later, and from Halle it is about an hour to 'Jena Paradies'.
By train from Leipzig/Halle Airport (LEJ):
LEJ via Halle(Saale)/Leipzig (2x per hour, 1 changes, >1.5h travel time, arrival: 'Jena Paradies')
Typically you take the city train (S5 or S5X) to Halle (Saale) main station ('Halle(Saale) Hbf'). From there, regional trains (towards 'Jena-Göschwitz' or 'Saalfeld') take you directly to 'Jena Paradies'. This will take about one and a half hours.
By (rental) car:
First find out your route here. At the end take the autobahn A4 (sometimes called BAB 4) and leave it at 'Jena-Zentrum'. Then follow the freeway to the North towards 'Jena-Zentrum' for about 10 minutes.
If you need a rental car, you can check the prices and conditions here.
Map
Venue
The meeting will be held at the Normannenhaus in Jena. The venue is located close to the city center, offering a nice view.
Jena is a university city with about 110,000 inhabitants (of which about 25,000 are university students), located in the central part of Germany, in the state of Thuringia, between Berlin (250 km), Frankfurt/Main (310 km), Leipzig (100 km), Dresden (190 km), and Munich (380 km). Jena, self-styled "Lichtstadt" ("City of Light"), is proud of having won the all-German competition to get the title "City of Science 2008". More information about Jena can be found at www.visit-jena.de.
