Constraints on the location of a possible 9th planet derived from the Cassini data
A. Fienga, J. Laskar, H. Manche +1
To explain the unusual distribution of Kuiper Belt objects, several authors have advocated the existence of a super-Earth planet in the outer solar system. It has recently been pro…
Tests of General relativity with planetary orbits and Monte Carlo simulations
A. Fienga, J. Laskar, P. Exertier +2
Based on the new developped planetary ephemerides INPOP13c, determinations of acceptable intervals of General Relativity violation in considering simultaneously the PPN parameters…
INPOP new release: INPOP13b
A. Fienga, H. Manche, J. Laskar +2
Based on the use of MESSENGER radiotracking data in the construction of new Mercury ephemerides (Verma et al. 2014) a new planetary ephemerides INPOP13b was built including Mercury…
Use of MESSENGER radioscience data to improve planetary ephemeris and to test general relativity
Ashok Verma, Agnes Fienga, Jacques Laskar +2
The current knowledge of Mercury orbit has mainly been gained by direct radar ranging obtained from the 60s to 1998 and by five Mercury flybys made by Mariner 10 in the 70s, and ME…
The INPOP10a planetary ephemeris and its applications in fundamental physics
A. Fienga, J. Laskar, P. Kuchynka +5
Compared to the previous INPOP versions, the INPOP10a planetary and lunar ephemeris has several improvements. For the planets of our solar system, no big change was brought in the…
La2010: A new orbital solution for the long term motion of the Earth
J. Laskar, A. Fienga, M. Gastineau +1
We present here a new solution for the astronomical computation of the orbital motion of the Earth spanning from 0 to -250 Myr. The main improvement with respect to the previous nu…
