A general relativistic model for the light propagation in the gravitational field of the Solar System: the dynamical case
Fernando de Felice, Alberto Vecchiato, Maria Teresa Crosta +2
Modern astrometry is based on angular measurements at the micro-arcsecond level. At this accuracy a fully general relativistic treatment of the data reduction is required. This pap…
Micro-arcsecond light bending by Jupiter
MT Crosta, F Mignard
The detectors designed for Gaia, the next ESA space astrometry mission to be launched in 2011, will allow to observe repeatedly stars very close to Jupiter's limb. This will open a…
A General Relativistic Model of Light Propagation in the Gravitational Field of the Solar System: the Static Case
F. de Felice, M. T. Crosta, A. Vecchiato +2
We develop here a new approach for the relativistic modeling of the photons moving into a quasi-Minkowskian space-time, where the metric is generated by an arbitrary n-body distrib…
Some aspects of Relativistic Astrometry from within the Solar System
Maria Teresa Crosta, Alberto Vecchiato, Fernando de Felice +2
In this article we outline the structure of a general relativistic astrometric model which has been developed to deduce the position and proper motion of stars from 1-microarcsecon…
Testing general relativity by micro-arcsecond global astrometry
Alberto Vecchiato, Mario G. Lattanzi, Beatrice Bucciarelli +3
The global astrometric observations of a GAIA-like satellite were modeled within the PPN formulation of Post-Newtonian gravitation. An extensive experimental campaign based on real…
