SYMPOSIUM UAI NUMBER 172
DYNAMICS, EPHEMERIDES AND ASTRONOMETRY OF THE SOLAR SYSTEM

SCIENTIFIC PROGRAM

The aim of this symposium is to gather astronomers interested in the current knowledge of the solar system. The following topics will be covered :

  • dynamics : evolution of the system, chaotic behaviour, relativistic effects, analytical and numerical theories of planets, natural satellites and small bodies;
  • mathematical techniques : symplectic mappings, elliptic functions and algebraic manipulators;
  • ephemerides : limits of predictability (resonance and chaos), accurate short term and long term predictions, real-time update, optimal representations, numerical integration, near-Earth objects;
  • observations : astrometry from space, ground-based astrometric observations of high accuracy (CCD, optical interferometry, VLA, VLBI, radar, lunar laser ranging results and pulsar timings connected to solar system ephemerides);
  • dynamical reference system and astronomical standards.

This symposium was organized in connection with the celebration of the bicentenary of Bureau des longitudes and historical aspects of the progress in celestial mechanics and in ephemerides will be covered during the symposium by invited lectures under the presidency of J. Kovalevsky.
