Prospective Graduate Students and Postdocs: Please contact me about opportunities for research in planetary science and shock physics. Note that our graduate program admission deadline is December 15 (late applications will be considered). A postdoc ad will be posted shortly.

Sarah Stewart’s research group investigates the formation and evolution of planetary bodies. Our primary techniques are shock wave experiments to measure material properties and numerical simulations of planetary processes. We tackle a broad range of problems in planetary science by focusing on understanding the feedbacks between physical processes and changes in material properties.

New Tidal Evolution Model for the Moon

We have a new model for the tidal evolution of the Moon, published in Nature. The model begins with a giant impact that tilts the Earth about 70 degrees from the ecliptic. Learn more about the Origin of the Moon. (Image from eskipaper.com)

Tidal Evolution of the Moon: Earth started tilted over

October 31st, 2016|Comments Off on Tidal Evolution of the Moon: Earth started tilted over

Our new model for the tidal evolution of the moon was published online today in Nature: Tidal Evolution of the Moon from a high-obliquity, high-angular-momentum Earth. The tidal evolution is a big piece of the [...]
