![]() The duo's analysis has upended old views of the belt. "What we see today in the asteroid belt is sort of this melting pot of asteroids that formed in all different locations throughout the solar system," DeMeo says. Many of the rocks looked like they'd come from somewhere outside the asteroid belt. N2 - The field of asteroid thermophysical modeling has experienced anĪB - The field of asteroid thermophysical modeling has experienced anWhen DeMeo and her co-author, Benoit Carry of the Paris Observatory, looked at all of these new asteroids, they found something surprising. This will require a high level of sophistication of thermophysical models in order to analyze high-quality spacecraft data.", ![]() Asteroid space missions with thermal infrared instruments are currently undergoing study at all major space agencies. The radiative heating of asteroids, meteoroids, and comets from the Sun also governs the thermal stress in surface material only recently has it been recognized as a significant weathering process. Thermal inertia also governs non-gravitational effects on asteroid orbits, requiring thermophysical modeling for precise asteroid dynamical studies. We discuss how instrumentation advances now allow mid-infrared interferometric observations as well as high-accuracy spectro-photometry, posing their own set of thermal-modeling challenges.We present major breakthroughs achieved in studies of the thermal inertia, a sensitive indicator for the nature of asteroids soils, allowing us, for instance, to determine the grain size of asteroidal regoliths. ![]() Thermophysical modeling led to asteroid size estimates that were confirmed at the few-percent level by later spacecraft visits. These parameters can therefore be derived by thermophysical modeling of infrared data. The infrared emission of asteroids depends on the body's size, shape, albedo, thermal inertia, roughness and rotational properties.
