A receipt of registration fee will be provided to each registered participant during the meeting. Cancellation: cancellation with reimbursement will only be possible until October 11th, 2013 (10 days before the start of the meeting). In such a case, registration fees will be reimbursed with the exception of a small management fee. If the cancellation happens during the last 10 days before the meeting, no reimbursement will be possible.

Proceedings of the Rencontres 2013

The Proceedings of the Rencontres will be published in the MemSAIt, from LaTeX files provided by the authors. Instructions for the manuscripts will be communicated later.


You will find here general information about subway and bus of Paris and about the trains.


There are several important events in Paris in October and it can be difficult to find an hotel at the last minute. Participants are requested to make their own reservation as soon as possible.The place of the meeting, building of the CNRS in Meudon is close to both (see the map):




  1. the station Bellevue (about 200m) of the train "transilien N" (from Paris-Montparnasse to Rambouillet, Dreux, Mantes la Jolie) etc. (here the timetable)  (see the stations).
  2. the station Brimborion (about 700m) of the tramway "T2" (see the stations) by the "chemin des Lacets" (but the slope to climb the hill is rather steep).


There are no convenient hotels in Meudon. You can choose to book an hotel:

  • -in Paris close to "Gare Montparnasse" and you will come to Meudon, station Bellevue, by train (1 train every 15mn for a trip of about 12 mn). It's probably the best solution but the hotels in Paris are more expensive.
  • -in Issy les Moulineaux and you will come to Meudon, station Brimborion, by tram (1 tram every 7 mn for a trip of about 6 mn). [If you want to go to Paris-Porte de Versailles from your hotel by tram, it will take 10mn.]
  • -in Suresnes and you will come to Meudon, station Brimborion, by tram (1 tram every 7 mn for a trip of about 10 mn). [If you want to go to Paris-Porte de Versailles from your hotel by tram, it will take 25mn.]

A list of convenient hotels in Paris close to Gare Montparnasse, in Issy les Moulineaux and in Suresnes is available hereBest rates are often available by direct online booking.

Selecting an hotel and making reservation is also possible on line using one of the following web sites: Hotels in Paris (click on district 14 or 15), or



Rencontres de l'Observatoire de Paris 2013 - ESO Workshop

Metal Production and Distribution in a Hierarchical Universe


Metals trace the full evolution of the Universe: from primordial Helium and Lithium in the big-bang nucleosynthesis to all heavier elements produced in stars and explosive events. Determining their relative abundances in different environments, and across cosmic time, reveals the underlying star  formation history and gas exchange processes. Recent progress in instrumentation and modeling now permits using metal production and distribution to test our ideas of galaxy evolution at many different hierarchical scales: from stellar clusters to clusters of galaxies. The hierarchical build up of present-day structures at different redshifts can also be followed, which go in parallel with the build-up of stellar and metal mass. These processes are interwoven: during most of cosmic history metal production happens at stellar scales, but metal distribution is effective on spatial scales covering several orders of magnitudes. Therefore simulations require exceptional computational power, and tracing metals across cosmic time needs an equivalent investment in observational facilities. Both aspects are reaching some maturity in these days, so we propose a meeting to review the state of the art in all the different research areas. Possible meeting sessions and invited speakers are listed below and above.



The workshop will take place at the "Espace Isadora Duncan" in Meudon.

In the beginning of the Nineteenth Century the "Pavillon Bellevue" was owned by the "Compagnie des grands hotels" . In 1907 they sold the "Pavillon" to Louis Auguste Paillard, a well known owner of several restaurants in Paris. He greatly improved the quality of the hotel, which became known as the "Paillard-Bellevue-Palace.


We will have our meeting in the "Pompadour Dining Room" of the former Palace, which had an impressive view of the Seine, the Eiffel Tower and the Mount Valerien.


The Palace was never profitable, and in 1913 Paillard sold it to a rich American English industrialist called Eugene Paris Singer. He was the lover of an American dancer, the Californian born Isadora Duncan. She had a very modern view of the art of dance, and enjoyed improvisation, and developing her own ideas. She thought that her mission on Earth was the creation of beauty, and the education of the young.


She opened a school in Bellevue to teach young women the art of dance, and used the large dining room as a dance hall. Unfortunately, the school was soon closed due to the outbreak of World War I in 1914... During the war the "Pavillon de Bellevue" became a hospital for war casualties, particularly for American troops.

After the war, in 1919, the "Direction Nationale des Recherches Scientifiques" was created, and the "Pavillon Bellevue" became a research centre. It has been completely renovated last year.
