摘要

ESPaDOnS is the new-generation stellar spectro-polarimeter designed and built, at the Observatoire Midi-Pyrenees. It is now installed at. the Canada-France-Hawaii Telescope (CFHT) and fully operational. The instrument matches the expected performances, and is available to the community since February 2005. Several major scientific results, on young, cool and hot stars, and on protostellar accretion disks in particular, are already published, in press, or submitted.
