MOSES -- The MONET Star and Exoplanet Spectrograph
S. Schäfer, L. Schmidt, H. Anwand-Heerwart +2
We introduce MOSES, the new High-Resolution Echelle Spectrograph designated for the 1.2m MONET telescope at McDonald Observatory, Texas, USA. The science drivers are radial velocit…
Observing the integrated and spatially resolved Sun with ultra-high spectral resolution
S. Schäfer, K. Royen, A. Huster Zapke +2
The Institute for Astrophysics Göttingen operates a solar observatory that combines a 50\,cm siderostat with (1) a vacuum vertical telescope, (2) a very high resolution Fourier Tra…
Fiber-coupling of Fourier Transform Spectrographs
S. Schäfer, P. Huke, D. Meyer +1
Fourier Transform Spectrographs (FTS) are versatile tools for measuring accurate, high resolution spectra. They are internally calibrated by a reference laser that runs in parallel…
Two Fabry-Perots and two calibration units for CARMENES
Sebastian Schafer, Eike W. Günther, Ansgar Reiners +3
The wavelength calibration and nightly drift measurements for CARMENES (Calar Alto high-Resolution search for M dwarfs with Exoearths with Near-infrared and optical Echelle Spectro…
