ANDES, the high resolution spectrograph for the ELT: science goals, project overview and future developments
A. Marconi, M. Abreu, V. Adibekyan +286
The first generation of ELT instruments includes an optical-infrared high-resolution spectrograph, indicated as ELT-HIRES and recently christened ANDES (ArmazoNes high Dispersion E…
Multi-purpose InSTRument for Astronomy at Low-resolution: MISTRAL@OHP
J. Schmitt, C. Adami, M. Dennefeld +31
MISTRAL is the new Faint Object Spectroscopic Camera mounted at the folded Cassegrain focus of the 1.93m telescope of Haute-Provence Observatory. We describe the design and compone…
Overview of the Instrumentation for the Dark Energy Spectroscopic Instrument

Calibration unit for the near-infrared spectropolarimeter SPIRou
I. Boisse, S. Perruchot, F. Bouchy +4
SPIRou is a near-infrared spectropolarimeter and high precision radial velocity instrument, to be implemented at CFHT in end 2017. It focuses on the search for Earth-like planets a…
SOPHIE+: First results of an octagonal-section fiber for high-precision radial velocity measurements
F. Bouchy, R. F. Diaz, G. Hébrard +5
High-precision spectrographs play a key role in exoplanet searches and Doppler asteroseismology using the radial velocity technique. The 1 m/s level of precision requires very high…
Higher-precision radial velocity measurements with the SOPHIE spectrograph using octagonal-section fibers
S. Perruchot, F. Bouchy, B. Chazelas +12
High-precision spectrographs play a key role in exoplanet searches using the radial velocity technique. But at the accuracy level of 1 m.s-1, required for super-Earth characterizat…
Consequences of spectrograph illumination for the accuracy of radial-velocimetry
I. Boisse, F. Bouchy, B. Chazelas +4
For fiber-fed spectrographs with a stable external wavelength source, scrambling properties of optical fibers and, homogeneity and stability of the instrument illumination are impo…
