Conference poster   (full size)



The proceedings will be published in the ASP Conference Series. You can download the macros from the Astronomical Society of the Pacific website.  The deadline for submission of the texts will be october 31, 2003, sharp. We intend to have the proceedings published quickly, therefore we encourage you to meet the deadline. We invite you to send the .tex and the attached postscript files to the email adress col2003@iap.fr stating clearly in the subject the name of the first author.

The page limitation will be 12 pages for review talks, 8 pages for oral contributions, 2 pages for posters. We will accept only one contribution per registered participant to the colloquium.

Photos were taken during the conferences, and they can be found here for download.

Paris, September 23, 2003     



 The "ULP Multimedia" department of the Louis Pasteur University (Strasbourg) has the responsability to broadcast the 2003 IAP colloquium on the Web channel "Canal-U" (http://www.canalc2.tv/video.asp?idvideo=2017).

ULP Multimedia has filmed the full colloquium from June 30th to July 4th, 2003. The speechs have been recorded and broadcasted in live through the Internet.  The recorded speechs are now also visible on the Canal-U channel "Colloques and Conferences".



Since the discovery of the first extrasolar planets orbiting a star in the mid-90's, more than a hundred objects have been detected which have been given the status of giant planet.Most of them have been found by the radial velocity method, and the large number of "planet candidates" detected by transits are waiting for spectroscopic confirmation. The observation of periodic transits appears to be a powerful tool with which to scrutinize these planets in detail, as well as to search for their atmospheres and exospheres. Several of these objects are in multiple systems.

Until recently, only planets with characteristics very different from those of the planets of our own solar system were reported. Many of these orbits had very small semi-major axes, and those that did not had large eccentricity. Now, long term searches are discovering Jupiter-mass planets with circular orbits and semi-major axes of several astronomical units. These discoveries have brought the field of planetary sciences to the front rank of observational and theoretical astrophysics, triggering an unprecedented effort to understand more fully the observed systems, and to detect a broader class of objects, especially terrestrial planets. An international conference bringing together theorists and observers is very timely. Many observational programs are being developed which will become operational in the years to come. It seems likely that they will lead, in the next decade, to the detection of terrestrial planets. It also seems likely that they will provide the first evidence for the formation of planets in gaseous discs around young stars.

On the theoretical side, very important progresses have been made in the understanding of the dynamics of planets in discs and in multiple systems. However, many fundamental issues regarding, for instance, planetary formation, still remain uncertain. The conference is designed to be a forum for the presentation of observational and theoretical results. For advances in this young field to continue, it is particularly important that observers and theorists interact with each other, and conferences are the most natural venue for these contacts. Finally, and not least, the conference will be a conduit for recent discoveries to be announced to the community.

The conference will cover the following topics:

- Detections of extra-solar planets: Methods, results and programs

- Extra-solar planets images and spectroscopy

- Planetary systems properties

- Atmospheres and exosphere of extra-solar planets

- Extra-solar comets

- Planetary systems evolution

- Protoplanetary and planetary disks: structure, properties and evolution

- Planetary formation

- Interaction between disks and planets

- Dynamics of multiple planetary systems


There will be both invited and contributed talks, as well as poster presentations.

    Registration is closed. The final list of participants has been released.

    If you are registered, you can update your informations, or cancel your participation.

     We ask people whose application has been accepted and who finally decide not to attend the conference to notify us as quickly as possible.

    The registration fee is 200 euros. It is payable either in cash or by traveler or personal check at the time of registration. This fee includes the proceedings, the banquet and the buffet/coktail, but NOT lunches. Tickets for the local restaurant will  be sold at the time of registration. Registration will start on Sunday, June 29 at 5.00 pm, in the lobby of the Institut d'Astrophysique de Paris. Informations on how to access IAP can be found here.

    The access to the different talks of the conference will be very strictly limited to registered participants since we have reached the absolute maximal capacity of the conference room.



     The hotels in this list are located close to IAP (in some cases, the tenant will be willing to give a discount for participants: make sure to ask and mention that you are attending a conference at IAP!). Participants must book their hotel as soon as possible.
