SUMMARY:High-resolution optical spectroscopy for everyone: want a PEPSI?
DESCRIPTION:High-resolution optical spectroscopy for everyone: want a PEPSI
 ?\nProf. Klaus G. Strassmeier\n\nThe demand of high-res spectroscopy had s
 een a tremendous increase after  the discovery of exoplanets. Such instrum
 ents are now among the  standard equipment of nearly every observatory. Th
 e latest addition in  the zoo is PEPSI, the new bench-mounted fiber-fed an
 d stabilized  “Potsdam Echelle Polarimetric and Spectroscopic Instru
 ment” for the  11.8m Large Binocular Telescope (LBT). It covers the 
 entire optical  wavelength range from 383 to 914 nm in three exposures at 
 resolutions of  either R=λ/Δλ=50,000, 130,000 or 250,0
 00. As of this year, the  R=130,000 mode can also be used with two dual-be
 am Stokes IQUV  polarimeters and as such provides another unique capabilit
 y besides the  ultra-high resolution mode. It is also fiber linked to a  d
 isk-integration solar telescope and the Vatican Observatory's 1.8m  VATT. 
 In this talk I introduce the instrument and focus on first data  and resul
 ts in order to "feel the taste". Among the first targets were  the Sun and
  solar twins, Gaia benchmark stars, Jupiter's Io, planet-host  stars with 
 hot Jupiters as well as stars with Earth-sized planets,  novae, the ISM, a
 nd much more.
