[PPS06-P01] Studying Martian interior structure by using geodesic data

We inverted the Martian interior structure by using geodesic data, including Love number k₂ and tidal response factor Q. We used model parameters (Vs, Vp) obtained from the Insight mission to calculate the grain-size distribution of the Martian mantle by combining four rheology models (Maxwell, Andrade, Burgers, and Sundberg-Cooper). We found the grain size is generally larger than the Martian meteorolite found on the Earth.
