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 Tr…
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…
