... 26, 1997) and that of the Hale-Boppcomet (observed on March 30, 1997 with the same ... 3429 Swan band head (0;1) at =5635? with that for the Hale-Boppcomet nuclei ... emission bands in the spectra of our supergiant and of the Hale-Boppcomet nucleus ...
... Comparison with the spectrum of the Hale-Boppcomet leads us to propose that in both cases the same mechanism (resonance fluorescence) is responsible for the emission in the molecular bands. ...
... emission of molecular lines discovered in the spectra of IRAS04296 and its similarity to the emission of the Hale-Boppcomet allow us to suggest that in both cases the same mechanism (the resonance fluorescence) is responsible for the observed features ...
... In Sect.2 we describe our observational material for IRAS04296 and discuss its molecular features, comparing them with the corresponding spectrum of the Hale-Boppcomet. ...
