Hi-5 kickoff meeting

Hi-5 is the name of a new instrumental project for the Very Large Telescope Interferometer (VLTI). The main objectives of Hi-5 are to study at high-contrast and high-angular resolution nearby planetary systems (forming exoplanets and exozodiacal disks) and bright extragalactic objects (AGNs) in the L and M bands (3 to 5 microns). The possibility to do high-contrast interferometric observations in the L and M bands with the VLTI has recently emerged due to developments in integrated optics, an essential component of current VLTI instruments operating at shorter wavelengths (such as PIONIER and GRAVITY). The goal of the kickoff meeting will be to officially start the Hi-5 project and to plan upcoming activities and collaborations in order to bring the instrument at the VLTI on relatively short timescales . The meeting will take place at the University of Liège (downtown) on October 2 and 3 2017 (more info here ). If you want to participate in this meeting, please contact us .

Venue

The Hi-5 meeting will take place at the downtown campus of the University of Liège (see address and map below).


To reach the meeting by plane , there are several options (connections, flight frequency and fares will vary according to your departure city):

  • Brussels Airport (largest and best connected airport of Belgium, train station inside the airport)
  • Charleroi/Brussels South Airport (many low-cost options)
  • Liège Airport (the closest airport, but limited number of destinations)
  • Maastricht Airport (located in the Netherlands, but not so far from Liège)


Once arrived at one of these airports, the easiest way to reach Liège by train is to arrive first at the Liège-Guillemins station, that is well connected to many Belgian, Dutch, German, French and British cities. From there, you may either continue your trip by train (5 min.) to the Liège-Palais train station (in which case you should have bought a train ticket with that final destination) or take a taxi or public bus from the Liège-Guillemins station and go to your hotel or to the meeting place (Liège University, Place du XX Août 7, downtown).





Accommodation Here are some suggestions for hotels located near the meeting and the Liège-Palais train station:
