Constraints on the Lunar Interior Through Comparison of Observed Apollo Seismic Travel Time With Simulated Lunar Interiors
Understanding the current state of the lunar interior is key to evaluating its formation history and evolution. The analyses of seismic waves recorded by 5 years of the Apollo passive seismic network, from 1972-1977, have provided some fundamental constraints on the lunar interior structure. Here, we show that comparisons between (a) calculated seismic velocities of simulated lunar interiors and (b) measured Apollo seismic velocities can resolve new solutions. Specifically, we show that comparison of seismic travel times can be used to constrain the lower bound of possible selenotherms.
