From: Mars core structure—concise review and anticipated insights from InSight
Radial wavespeed and density profiles of two Mars internal structure models, Rivoldini et al. (2011) (R11DW black) and Sohl and Spohn (1997) (SS97a gray). The most pronounced difference between them is their core size. Other important seismological details are that R11DW’s core wavespeed is lower than V S at the base of the mantle, whereas SS97a’s is slightly higher
