CHARA Year Five Science Review

Hosted by l'Observatoire de la Côte d'Azur / Nice Observatory

Nice, France

March 16-18, 2009


Although there was not a gathering of the CHARA Collaboration in 2008, we made up for that omission with a wonderful three-day meeting to review our fifth year of CHARA Array science at the Nice Observatory. The meeting was graciously hosted by the Observatoire de la Côte d'Azur and the Laboratoire FIZEAU.

The scientific program was organized by Theo ten Brummelaar, CHARA's Associate Director. The local arrangements were beautifully and memorably managed by Denis Mourard and Phillipe Stee of OCA, and we thank them for making the Nice Observatory such a spectacular and hospitable venue for this meeting. We also gratefully acknowledge the Observatoire de la Côte d'Azur, the Laboratoire FIZEAU, the Université de Nice, and the CNRS (Programme National de Physique Stellaire et Action Spécifique Haute Résolution Angulaire) for their generous financial support that was critical for enabling this invigorating meeting.

The participants in "CHARA Year Five" are shown in the photograph and key below.
