  • Research Areas

    Sean Lindsay is an expert at computationally modeling the optical properties (absorption and scattering efficiencies) of cosmic crystalline silicates. His PhD dissertation pioneered modeling the absorption efficiencies for forsterite grains for polyhedral shapes and many grain sizes. These models are now used by a variety of researchers to model the thermal flux of dust in comet comae and asteroid surface environments. His expertise includes: 1) spectroscopic performing mineralogical analyses of small body surfaces using visible, nearand mid-infrared spectroscopic data; and 2) modeling the thermal gradient and mid-infrared emissivity of porous regolith surfaces on airless bodies. His primary research is on determining the mineralogy and relative abundances of dust species for the small bodies of the Solar System (SS) to understand the origins and evolution of the SS small bodies.
