Global Astrometry With The Space Interferometry Mission

, 2005
In this paper we will discuss the prospects for global astrometric measurements with the Space Interferometry Mission (SIM). SIM will perform four microarcsec astrometric measurements on objects as dim as 20th magnitude using optical interferometric ...

ELSA and the Frontiers of Astrometry [PDF]

EAS Publications Series, 2010
ELSA stands for the ambitious goal of `European Leadership in Space Astrometry'. In this closing contribution I will examine how the ELSA network has advanced this goal. I also look ahead to the time when the Gaia data will be published and consider what needs to be done to maintain European leadership.

Micro-Arcsecond Radio Astrometry

, 2014
Astrometry provides the foundation for astrophysics. Accurate positions are required for the association of sources detected at different times or wavelengths, and distances are essential to estimate the size, luminosity, mass, and ages of most objects ...

Observing exoplanet populations with high-precision astrometry

, 2012
This thesis deals with the application of the astrometry technique, consisting in measuring the position of a star in the plane of the sky, for the discovery and characterisation of extra-solar planets.

High-precision astrometry with VVV

Aims. We use near-infrared, ground-based data from the VISTA Variables in the Via Lactea (VVV) survey to indirectly extend the astrometry provided by the Gaia catalog to objects in heavily extinct regions toward the Galactic bulge and plane that are ...

Spectral Astrometry Mission for Planets Detection

, 2002
The Spectral Astrometry Mission is a space-mission concept that uses simultaneous, multiple-star differential astrometry to measure exo-solar planet masses. The goal of SAM is to measure the reflex motions of hundreds of nearby ({approx}50 pc) F, G and K

A project of teaching ground-based astrometry

, 2007
International audienceThe optical ground-based astrometry of solar system objects may have its accuracy strongly improved by using new methods for making observations and reductions of them.
