Abstract

Precise astronomical spectroscopy with the forthcoming E-ELT and its High Resolution Spectrograph (HIRES) will enable detection of atmospheres of exoplanets. HIRES will experience systematic errors like intrapixel variations and random variations like fiber noise, caused by the non-uniform illumination of the coupling fibers. All these errors will affect the performance of the spectrograph. One goal is to achieve a radial velocity precision on the order of 10 cms−1. Here, we describe the requirements for calibration sources which may be used for HIRES. Precise wavelength calibration with Laser Frequency Combs (LFC), so called AstroCombs, has been demonstrated with different astronomical spectrographs and we show a comparison of currently used AstroCombs. We outline a possible solution to meet the requirements of HIRES with a single broadband AstroComb.
