Because of this, up-...
The authors present far-ultraviolet images of comet Halley obtained from sounding rockets launched on 24 February and 13 March 1986. The authors gained direct electrographic images of the hydrogen coma of the comet at the Lyman-α wavelength (1,216 ), and objective spectra containing images of ...
Periodic Comet Halley (1982i)NH 2High-spectral-resolution line profiles and images of comet Halley were obtained in 1986 at the National Solar Observatory McMath telescope, using a dual-etalon Fabry-Perot spectrometer. The spectrometer was designed to obtain data in four distinct modes: (1) ...
The spacecraft images of Comet Halley's nucleus have been analyzed to characterize the positions of the nucleus during the Vega 1, Vega 2, and Giotto flybys. Then the mean instantaneous rotations axes compatible with each pair of positions were calculated. The comparison with ground-based ...
