A new determination of lunar orbital parameters, precession constant and tidal acceleration from LLR measurements

- J. Chapront, M. Chapront-Touzé, G. Francou
- Physics
- 1 May 2002

An analysis of Lunar Laser Ranging (LLR) observations from January 1972 until April 2001 has been performed, and a new solution for the lunar orbital motion and librations has been constructed that… Expand

Expressions for IAU 2000 precession quantities

- N. Capitaine, P. Wallace, J. Chapront
- Physics
- 1 December 2003

A new precession-nutation model for the Celestial Intermediate Pole (CIP) was adopted by the IAU in 2000 (Resolution B1.6). The model, designated IAU 2000A, includes a nutation series for a non-rigid… Expand

Numerical expressions for precession formulae and mean elements for the Moon and the planets.

- J. Simon, P. Bretagnon, J. Chapront, M. Chapront-Touzé, G. Francou, J. Laskar
- Physics
- 1 February 1994

We present, in this paper, a coherent set of formulae giving numerical expressions for precession quantities and mean elements of the Moon and the planets. First, using the notations of Lieske et al.… Expand

Report of the International Astronomical Union Division I Working Group on Precession and the Ecliptic

- J. Hilton, N. Capitaine, +10 authors J. Williams
- Physics
- 1 March 2006

The IAU Working Group on Precession and the Equinox looked at several solutions for replacing the precession part of the IAU 2000A precession–nutation model, which is not consistent with dynamical… Expand

Improvement of the IAU 2000 precession model

- N. Capitaine, P. Wallace, J. Chapront
- Physics
- 1 March 2005

The IAU 2000 precession consists of the IAU 1976 ecliptic precession (Lieske et al. 1977, AA the model is recalled in Tables 3−5. Due to the strong dependence of the precession expressions on the… Expand

ELP 2000-85: a semi-analytical lunar ephemeris adequate for historical times

- M. Chapront-Touzé, J. Chapront
- Physics
- 1988

The lunar ephemeris ELP 2000.

- M. Chapront-Touzé, J. Chapront
- Physics
- 1 August 1983

The lunar theory ELP revisited. Introduction of new planetary perturbations

- J. Chapront, G. Francou
- Physics
- 1 June 2003

On the basis of the semi-analytical theory ELP, a new solution has been built that makes use of the planetary perturbations MPP01 constructed by P. Bidart. This new solution, called ELP/MPP02, is an… Expand

Expressions for the Celestial Intermediate Pole and Celestial Ephemeris Origin consistent with the IAU 2000A precession-nutation model

- N. Capitaine, J. Chapront, S. Lambert, P. Wallace
- Physics
- 1 March 2003

Expressions for the position of the Celestial Intermediate Pole (CIP) and the Celestial Ephemeris Origin (CEO) in the Geocentric Celestial Reference System (GCRS) have been computed using the IAU… Expand

Planetary theories with the aid of the expansions of elliptic functions

- J. Chapront, J. Simon
- Mathematics
- 1 June 1995

For coplanar circular orbits, the mutual perturbations between two bodies can be expressed in term of the argument of Jacobian elliptic functions instead of the difference of the mean longitudes. For… Expand
