  "description": "<p>CRIRES+ is the fully refurbished and greatly enhanced near-infrared CRyogenic high-resolution Infrared Echelle Spectrograph (CRIRES) that will be offered to the entire astronomical community in 2021. CRIRES+ combines high spectral resolution and full near-infrared coverage, and enables a variety of long awaited scientific opportunities.</p>\n\n<p>CRIRES+ is an adaptive optics fed high-resolution (R~100000) near-infrared spectropolarimeter installed at one of the 8-m unit telescopes of the European Southern Observatory Very Large Telescope in Paranal, Chile. CRIRES+ operates in spectroscopy mode from 0.95 to 5.2 &mu;m (YJHKLM bands) and in spectropolarimetry mode between 0.95 and 2.5 &mu;m (YJHK). The instrument boasts an overall increase in efficiency compared to the original CRIRES, a tenfold increase in simultaneous wavelength coverage thanks to a new cross-dispersed design (now ~150 nm), and improved stability and repeatability. Additionally, a new powerful data reduction pipeline as well as new wavelength calibration capabilities including new gas cells and a Fabry-Perot etalon will allow to reach a few m/s in RV precision.</p>\n\n<p>The unique combination of the 8-m VLT collecting power, the R=100000 spectral resolution, and spectroscopic coverage up to 5.2 &mu;m makes CRIRES+ a game-changing instrument for the study of exoplanetary atmospheres, stellar magnetism, low-mass objects, and other science cases.</p>",
