Bonjour!

I am working as research engineer for the french CNRS research center at the Paris Observatory. Formerly, I have been working for the european astrometric satellite Hipparcos, successively on its Input Catalogue, then data processing, and finally contributing to its science exploitation. I am now involved in the preparation of the Gaia satellite since 1998.

So, in brief, my main field is astronomy. I defended my PhD in 1993 and my complete list of papers can be found on my web page or here on the NASA ADS.

Beside scientific papers, I have been involved for some time on the French Wikipédia, as user FredA, adding new articles when I have some spare time. Here, my main involvement is about binary stars, but my general competencies are also related to astrometry, galactic structure, statistics, etc.

Not completely unrelated, my main hobby is image processing.

Hi, in French now, for a multicultural CZ!

Je travaille comme ingénieur de recherche du CNRS à l'Observatoire de Paris. Précédemment, j'ai oeuvré sur le satellite astrométrique Hipparcos, d'abord sur son Catalogue d'Entrée, ensuite le traitement des données, et finalement l'exploitation scientifique des données. Je suis maintenant (depuis 1998) impliqué dans la préparation du satellite Gaia qui doit être lancé en 2011.

Donc, en clair, mon activité principale concerne l'astronomie. J'ai passé une thèse en 1993 et la liste complète de mes articles peut être trouvé sur ma page web ou ici sur le system NASA ADS.

En plus de ces papiers, j'ai été impliqué depuis un certain temps sur le Wikipédia (français), sous le pseudo FredA, ajoutant des articles à mes moments perdus. Ici, ma principale implication concerne les étoiles binaires, quoique je touche également à l'astrométrie, la structure galactique, les statistiques, etc.

Non sans rapport, mon principal hobby est le traitement d'image.

Frédéric (Fred)
