Abstract

We present a theoretical analysis of astrometric searches for extrasolar planets with the Space Interferometry Mission (SIM). In particular, we derive a model for future measurements with SIM and discuss the problem of reliable estimation of orbital elements of planets. For this purpose we propose a new method of data analysis and present a numerical test of its application to simulated SIM astrometric measurements of the ν And planetary system. We demonstrate that our approach allows for successful determination of its orbital elements. Most of the proposed approach can be adopted for other astrometric missions.
