The spectrum of star HR7235

The spectrum of star HR7235, straight from CRIRES.  The infrared light from the star was strongly dispersed by the spectrograph, spreading its colours from 2.89 μm to 2.97 μm (left to right) on the four detectors, that recorded the intensity of the light. The vertical lines correspond to features in the atmosphere, absorbing the light at specific colours. The images are peppered with many “hot pixels”, defects of the detectors that are removed by combining several spectra.
