[PPS10-13] Interior structure of Mars estimated from elastic properties of liquid Fe-Ni-S
Keywords:Mars, Core, liquid, sound velocity, density
Measured sound velocity (VP) of liquid Fe-Ni-S increased non-linearly with pressure and its pressure dependence is well fitted by the Birch-Murnaghan equation of state. Obtained bulk modulus of liquid Fe-Ni-S decreases with increasing sulfur content. Based on these obtained properties, we will discuss estimated radius and sulfur content of Martian core by comparison with observed moment of inertia data of Mars.
