AURELIE: the high resolution spectrometer of the Haute-Provence Observatory.
Abstract
A powerful and simple high resolution spectrometer has been developed and installed in 1989 at the Haute-Provence Observatory on the 1.52m telescope. It was designed primarily for high resolution (50000<R<110000) spectroscopy of point-like sources but medium resolutions down to 5000 are also available. The use of a Thomson TH 7832, a linear array CCD-like detector, provides the benefit of a very clean detector (no interference fringes or persistence effects). Due to the average seeing at OHP, a modified Bowen-Walraven image-slicer was used. The stability of the spectrometer is discussed together with its astrophysical performances.
