M. Roosserote et al., METALLIC EMISSION-LINES DURING THE IMPACT-L AND IMPACT-Q(1) OF COMET-P SHOEMAKER-LEVY-9 IN JUPITER, Geophysical research letters, 22(12), 1995, pp. 1621-1624
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 ob
servatory, France. The transient emission of seven emission lines from
five different metals (Na, Fe, Ca, Li, K) and of the H alpha line hav
e been identified in spectra from the fresh impact sites of fragments
L and and Q(1).
