ASTEROID ORBITS WITH GAIA: SIMULATED EXAMPLES

摘要

We apply the theoretical methods and numerical techniques to simulated Gaia observations and discuss the practical requirements for rapid real-time computation of orbits during the active observational phase of Gaia. We pay special attention to the nonlinear phase transition effect from extended orbital distributions to well-constrained ones in the case of high-precision data and illustrate the implications for Gaia with examples.
