Dr. Isamu Matsuyama

"Global figure and interior structure of the Moon"
Abstract:
The unusual shape of the Moon given its present rotational and orbital state has been explained as due to a fossil figure preserving a record of remnant rotational and tidal deformation. However, previous studies assume infinite rigidity and ignore deformation due to changes in the rotational and tidal potentials. I will present a physical model that takes into account this deformation.
One of the primary science objectives of the Gravity Recovery and Interior Laboratory (GRAIL) mission is to determine the structure of the lunar interior. In the second part of the talk, I will discuss the use of Bayesian probability theory and multiple geophysical constraints, including the anticipated improvement in the determination of the k2 Love number, to calculate the probability density function of interior structure parameters.
