- Abstract
It has been demonstrated for the first time in this paper that the frequently used approximation of the Andrade rheology with only one parameter is oversimplified and might lead to incorrect conclusions when studying the internal structure of the planets of the Solar System. Instead, we have used the Andrade rheology with two empirical parameters: α and ζ. The Earth's viscoelastic Love numbers for the principal lunar semidiurnal tide M2 were computed for two viscosity profiles and for 16 100 different combinations of α and ζ. The comparison of the computed Love numbers with the measured values makes it possible to constrain the range of values of both parameters that successfully describes the rheological properties of the Earth's mantle.
