Infrared observation of the nucleus of comet Halley with the IKS instrument from the VEGA 1 probe

The Infrared thermal emission of the nucleus has been observed by the imaging channel of the infrared spectrometer IKS during the fly-by of Comet Halley by the VEGA 1 probe. An emissive region with a temperature in excess of 300 K has been detected. The results are compatible with a simplified model...

Zusammenfassung:The Infrared thermal emission of the nucleus has been observed by the imaging channel of the infrared spectrometer IKS during the fly-by of Comet Halley by the VEGA 1 probe. An emissive region with a temperature in excess of 300 K has been detected. The results are compatible with a simplified model assuming a spherical nucleus covered by an insulating black material.
