Description:
The entry of interplanetary dust particles into Earth’s atmosphere deposits heavy elements at high altitudes, and may be observed in both gas phase and as a cloud layer. In this talk I will discuss a model for dust accretion onto close-in exoplanets, the stopping of the dust in the upper atmosphere, and the possible signatures of the heavy elements in transmission spectra.
Speaker: Phil Arras, University of Virginia
