Development of high resolution optical and near infrared astronomical spectrographs at the Observatory of Geneva
30-7-018 - Kjell Johnsen Auditorium
For well over 20 years, the Observatory of Geneva (Astronomy department of the University of Geneva) has been involved in the development of high resolution CCD-based spectrographs for astronomy use. In 1995, the 1st of these instruments has allowed the discovery of the world's first extra-solar planet and since then, several hundreds of extra-solar planets have been discovered and characterized by this instrument and its followers.
In this talk we will review the science case, the design and performances of these high-resolution high stability spectrograph through the different generations with a particular focus on the last ones: ESPRESSO currently in the final integration stage at the Observatory of Geneva and NIRPS; a fully cryogenic near infrared spectrograph to study the environment of cold M stars.
