Nouvelles correspondances entre les spectres des comètes et des étoiles N

Ultraviolet emissions observed in the nuclear regions of Comets 1941 I (CUNNINGHAM) and 1937 II (WILK-PELTIER) appear to coincide with the absorption features of the late N-stars in the same spectral region (λ 3 600-λ 3 850). This gives some evidence in favor of the assignment of the unidentified ultraviolet absorption bands of N-stars and of the unassigned cometary emissions to the same molecule, probably a polyatomic compound.
Coincidences of a less striking nature are found between the MERRILL-SANFORD bands of N-stars and unidentified cometary emissions in the region λ 4 200-λ 5 200.
