Thermal conductivities and diffusivities of porous ice samples at low pressures and temperatures and possible modes of heat transfer in near surface layers of comets.
Abstract
The authors report on direct measurements of the thermal conductivity of porous water ice and porous water ice/dust samples. They also summarize their estimates of the thermal diffusivities of porous water ice/dust samples and the ratio between water vapor and conductive heat transfer from interpretations of KOSI comet nucleus simulation experiments.
