Searching for substellar companion candidates with Gaia. III. Search for companions to members of young associations
A. -M. Lagrange, F. Kiefer, P. Rubini +13
Absolute astrometry with Gaia is expected to detect and characterize the orbits of thousands of exoplanets in the coming years. A tool, GaiaPMEX, was recently developed to characte…
Searching for substellar companion candidates with Gaia. II. A catalog of 9,698 planet candidate solar-type hosts
Flavien Kiefer, Anne-Marie Lagrange, Pascal Rubini +1
In a previous paper, we introduced a new tool called GaiaPMEX. It characterizes the mass and semi-major axis relative to the central star (sma) of a possible companion around any s…
Searching for substellar companion candidates with Gaia. I. Introducing the GaiaPMEX tool
Flavien Kiefer, Anne-Marie Lagrange, Pascal Rubini +1
The Gaia mission is expected to yield the detection of several thousands of exoplanets, perhaps at least doubling the number of known exoplanets. Although the harvest is expected t…
Planetary system architectures with low-mass inner planets: Direct imaging exploration of mature systems beyond 1 au
Celia Desgrange, Julien Milli, Gael Chauvin +20
The discovery of planets orbiting at less than 1 au from their host star and less massive than Saturn in various exoplanetary systems revolutionized our theories of planetary forma…
An imaged 15Mjup companion within a hierarchical quadruple system
A. Chomez, V. Squicciarini, A. -M. Lagrange +20
Since 2019, the direct imaging B-star Exoplanet Abundance Study (BEAST) at SPHERE@VLT has been scanning the surroundings of young B-type stars in order to ascertain the ultimate fr…
On the radial distribution of giant exoplanets at Solar System scales
A. -M. Lagrange, F. Philipot, P. Rubini +5
Context. Giant planets play a major role in multiple planetary systems. Knowing their demographics is important to test their overall impact on planetary systems formation. It is a…
Direct discovery of the inner exoplanet in the HD206893 system. Evidence for deuterium burning in a planetary-mass companion
S. Hinkley, S. Lacour, G. -D. Marleau +110
Long term precise radial velocity (RV) monitoring of the nearby star HD206893, as well as anomalies in the system proper motion, have suggested the presence of an additional, inner…
Direct confirmation of the radial-velocity planet Pic c
M. Nowak, S. Lacour, A. -M. Lagrange +90
Methods used to detect giant exoplanets can be broadly divided into two categories: indirect and direct. Indirect methods are more sensitive to planets with a small orbital period,…
