By liquid nitrogen immersion, we measured average low\u2010temperature heat capacities for 60 ordinary chondrite falls from the Vatican collection. We further characterized the temperature dependence of ordinary chondrite by direct measurement of Cp(T) over the range 5\u2013320 K for five OC falls, coupled by composition\u2010based models for 94 ordinary chondrites. We find that the heat capacity as a function of temperature for typical ordinary chondrites can be closely approximated by a third\u2010order polynomial in temperature. Furthermore, those polynomial coefficients can be estimated from the single\u2010value average heat capacity measurement. These measurements have important implications for the orbital and spin evolution of S\u2010 and Q\u2010type asteroids via the various Yarkovsky effects and the thermal evolution of meteorite parent bodies.”<\/p>\n","protected":false},"excerpt":{"rendered":"
