Spectrum of the known extrasolar planet host star
bHROS spectrum of the known extrasolar planet host star HD 82943 near the lithium doublet at 6707.8 angstroms. The spectrum (black points) is best fit with a model that indicates there is no appreciable 6Li present in the atmosphere of the star. The result helps rule out the role of external pollution from any extrasolar planet on the spectrum of the host star.
