From these, we have calculated their thermal diffusivity and thermal inertia values across this temperature range. For comparison, we also measured subsamples from two L chondrites (NWA 11038 and NWA 11344) at the same time, using the same methods. The thermal diffusivity results of the irons show a relatively constant value for T\u2009>\u2009100\u2009K with a characteristic low-temperature maxima at \u223c5\u2009K for the iron meteorites; by contrast, the diffusivities of the L chondrites fell by a factor of two over this range and reached low-temperature maxima at \u223c20\u2009K. Thermal inertia values show a crossover behavior, with a strong increase in thermal inertia as temperatures drop below 55\u2009K and a less dramatic change at higher temperatures. Our new diffusivity and inertia values cover a wider range of temperatures than previous literature data for iron meteorites. They also provide a useful ground truth in understanding remotely sensed thermal inertias of potentially metal-rich asteroids, including 16 Psyche, target of the NASA Psyche mission.”<\/p>\n","protected":false},"excerpt":{"rendered":"
