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.

Search for quasar pairs with Gaia astrometric data

Astronomy & Astrophysics
Quasar pairs, a special subclass of galaxy pairs, are valuable in the investigation of quasar interaction and clustering, the coevolution between the two quasars’ host galaxies, and the growth of supermassive black holes, as well as the formation and ...

GALACTICNUCLEUS: A high-angular-resolution JHKs imaging survey of the Galactic center

Astronomy & Astrophysics
Context. The center of the Milky Way presents a unique environment of fundamental astrophysical interest. However, its extreme crowding and extinction make this region particularly challenging to study.

A Curated Dataset of Regional Meteor Events with Simultaneous Optical and Infrasound Observations (2006–2011)

Data
We present a curated, openly accessible dataset of 71 regional meteor events simultaneously recorded by optical and infrasound instrumentation between 2006 and 2011. These events were captured during an observational campaign using the all-sky cameras of

Right round: Onset and long-term evolution of rotation in star clusters

Astronomy & Astrophysics
We present the results of a detailed kinematic analysis of a significant fraction of the known population of Galactic star clusters aimed at constraining the physical mechanisms driving the onset and evolution of cluster rotation.

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.
