The new lunar ephemeris INPOP17a and its application to fundamental physics

摘要

We present here the new INPOP lunar ephemeris, INPOP17a. This ephemeris isobtained through the numerical integration of the equations of motion and ofrotation of the Moon, fitted over 48 years of Lunar Laser Ranging (LLR) data.We also include the 2 years of infrared (IR) LLR data acquired at the Grassestation between 2015 and 2017. Tests of the universality of free fall areperformed. We find no violation of the principle of equivalence at the 10-14level. A new interpretation in the frame of dilaton theories is also proposed.
