High dispersion spectra of the outer planets- i. jupiter in the visual and red

摘要: Abstract Our high dispersion spectrograms of Jupiter partially resolve the red methane and ammonia bands show new, weak lines. At times Jovian gases do not co-rotate with cloud layer as evidenced by anomalous inclination their absorption The measures are discussed in detail. CH 4 lines λ 6190 band have been compared detail laboratory Saturnian counterparts. An upper limit to total pressure above is estimated; from these data a new H 2 abundance about 27 km-atm, H/He ratio deduced. We find H/C for Jupiter, Saturn, Uranus be far below corresponding Sun other stars. locations two tentatively ascribed given; search some absorbers this spectral region gave negative results.
