We kindly invite you to attend the ARIEL (Atmospheric Remote-Sensing Infrared Exoplanet Large-survey) science conference to be held at the University Foundation, Egmontstraat 11 rue d’Egmont, in Brussels (Belgium) on November 21-23, 2016.


ARIEL is one of the medium class mission candidates in the Cosmic Vision programme of the European Space Agency (ESA) to be launched in the 2026 timeframe. The selection of one of the three mission candidates is foreseen for mid 2017.

ARIEL will investigate the atmospheres of several hundreds of planets orbiting bright stars. During its four-year mission, ARIEL will observe exoplanets ranging from Jupiter- and Neptune-size down to super-Earth and Earth-size in a wide variety of environments. The main focus of the mission will be primarily on warm and hot planets in orbits close to their star. These exoplanets represent a natural laboratory in which to study the chemistry and formation of exoplanets, and hence the evolution of planetary systems. ARIEL will investigate their composition and chemical/physical properties through repeated, simultaneous, multi-wavelength, high photometric stability spectroscopic observations.

The Conference

This international conference will provide an overview of the ARIEL science and mission, including presenting the opportunities for the general community that ARIEL will offer, as well as providing a forum for discussion and feedback in advance of the ESA Cosmic Vision review process.

The ESA study and science teams will present the current ARIEL science case, mission objectives, technical concept, and data policies. The main goal of this public conference is to inform and receive critical feedback and contributions from the community covering all aspects of ARIEL; including, but not limited to, exoplanetary modelling, target selection, atmospheric retrieval and data processing, mission and instrument design and critical technologies. In addition, time will be set aside for dedicated poster sessions and open discussions.

Registration and abstracts

Registration is still open - select 'Registration' at the top of this page.  The program with oral contributions has been consolidated but we still accept additional poster contributions.

Registration fee for the conference will be 100,- Euro and includes lunches, coffee breaks and the conference welcome cocktail.  A limited number of student scholarships covering the conference fee is available.

We look forward to seeing you at the ARIEL conference in November!
