HST astrometry of the closest Brown Dwarfs -- II. Improved parameters and constraints on a third body
L. R. Bedin, J. Dietrich, A. J. Burgasser +5
Located at less than 2pc away, Luhman16AB (WISE.J104915.57-531906.1) is the closest pair of brown dwarfs and third closest `stellar' system to Earth. An exoplanet candidate in the…
Discovery of astrometric accelerations by dark companions in the globular cluster Centauri
Imants Platais, Johannes Sahlmann, Leo Girardi +6
We present results from the search for astrometric accelerations of stars in Centauri using 13 years of regularly-scheduled {\it Hubble Space Telescope} WFC3/UVIS calibration o…
An update of SB9 orbits using HERMES/Mercator radial velocities
Thibault Merle, Dimitri Pourbaix, Alain Jorissen +3
The Gaia mission is delivering a large number of astrometric orbits for binary stars. By combining these with spectroscopic orbits for systems with two observable spectra (SB2), it…
Gaia Data Release 3: Gaia scan-angle dependent signals and spurious periods
B. Holl, C. Fabricius, J. Portell +23
Context: Gaia DR3 time series data may contain spurious signals related to the time-dependent scan angle. Aims: We aim to explain the origin of scan-angle dependent signals and how…
Gaia Data Release 3: Surface brightness profiles of galaxies and host galaxies of quasars
C. Ducourant, A. Krone-Martins, L. Galluccio +13
Since July 2014, the Gaia space mission has been continuously scanning the sky and observing the extragalactic Universe with unprecedented spatial resolution in the optical domain…
Gaia Data Release 3. Astrometric binary star processing
Jean-Louis Halbwachs, Dimitri Pourbaix, Frédéric Arenou +6
Context.The Gaia Early Data Release 3 contained the positions, parallaxes and proper motions of 1.5 billion sources, among which some did not fit well the "single star" model. Bina…
