    Properties of dust in comet P/Halley measured by the Vega-2 three-channel spectrometer

    Optical properties of cometary dust exhibit no substantial variations at distances from 100 to 15 000 km from the nucleus. Dust ejection can be approximated by cos φ where φ is the angle with the sun-nucleus axis...

    Spectrophotometry of comet P/Halley at wavelengths 275—710 nm from Vega 2

    Spectrophotometric observations of the inner coma of comet Halley in the range 275-710 nm were conducted from Vega 2 on March 8, 9, 10, 11, 1986. During the encounter session, when the impact parameter was min...

    Spectroscopic study of comet Halley by the Vega 2 three-channel spectrometer

    The three-channel spectrometer (TKS) aboard the Vega 2 spacecraft recorded infrared and visible spectra near the nucleus of comet Halley. Spectra in the range 0.95–1.9 µm at a distance of 300 km from the nucle...

    Near-ultraviolet and visible spectrophotometry of comet Halley from Vega 2

    We report results obtained by the near-ultraviolet and visible channel (V) of the TKS instrument1 carried by Vega 2 during the hour preceding its closest approach to comet Halley. The brightness of the OH (0, 0) ...
