Selected science results
CRIRES can be used for a variety of science. A handful of science cases with published work are outlined below.
Exoplanet atmospheres
Snellen et al. (2010) found indications of CO in emission from the exoplanet orbiting HD 209458. The measurement is very difficult.Exoplanet radial velocities
Bean et al (2010) used a visitor gas cell and Figuera et al (2010) telluric lines to obtain radial velocity accuracies of <10 m/s of stars with exoplenets. Both papers postulate that some RV variations seen in the optical are caused by starspots and not planets.Methane and CO on Triton
CRIRES undertook one of the first observations since Voyager in 1989 and obtained the first detection of CO in the atmosphere of Triton. Seasonal variability was discovered. See Lellouch et al. (2010).Spectro-astrometry of protoplanetary discs
Pontoppidan et al. (2008) used spectro-astrometry of CO at 4.7 microns to obtain the position angle of the inner disc of protoplanetary discs with a spatial resolution of less than 1 Astronomical Unit.Stellar abundances
Johnsson et al. (2011) used the near-infrared line of Sulphur to study stellar abundances in the halo.
