IDENTIFICATION OF EMISSION BANDS IN P/HALLEY

Spectrophotometric studies of P/Halley (r = 1.98 AU, Δ = 1.19AU, r = 1.97, Δ = 1.16 AU and r = 1.95 AU, Δ = 1.13 AU) in the spectral range 3900 A – 6450 A were made on three nights and identifications of emission features include: CO+, C3, C2, CN, CH, NH2, H3, NaI, OI and H2O+ molecules. For the fir...

Zusammenfassung:Spectrophotometric studies of P/Halley (r = 1.98 AU, Δ = 1.19AU, r = 1.97, Δ = 1.16 AU and r = 1.95 AU, Δ = 1.13 AU) in the spectral range 3900 A – 6450 A were made on three nights and identifications of emission features include: CO+, C3, C2, CN, CH, NH2, H3, NaI, OI and H2O+ molecules. For the first time H3 molecule has been found in cometary atmospheres. Certain strong emission bands have been found in the spectra of P/Halley which are yet to be identified.
