Metallic emission lines during the impacts L and Q1 of comet P/Shoemaker Levy 9 in Jupiter

Abstract
High resolution spectroscopy of the impacts and impact sites of comet P/Shoemaker‐Levy 9 in Jupiter has been performed at the Pic‐du‐Midi observatory, France. The transient emission of seven emission lines from five different metals (Na, Fe, Ca, Li, K) and of the Hα line have been identified in spectra from the fresh impact sites of fragments L and Q1.
