"Spin-Down in a Laboratory Planetary Core"

by Matthew Adams

Friday, May 1, 2009 -- 12:00 p.m.
Large Conference Room, 1207 Energy Research Facility

Advisor:  Professor Daniel Lathrop

I have taken over the 60 cm laboratory device, formerly run by Doug Kelley. We use this device to study the behavior of rotating, conductive fluids in a geometry that approximates that of the core of the Earth. By this we hope to better understand the dynamo effect that gives rise to the magnetic fields found in many planetary and astrophysical bodies. I'll give an overview of ongoing work on spin-down, where the device is rapidly brought to a stop. This work is motivated by the libration of Mercury. I'll also talk briefly about other work motivated by results from the three-meter spherical-Couette water experiments.
