A temperate super-Jupiter imaged with JWST in the mid-infrared
E. C. Matthews, A. L. Carter, P. Pathak +16
Of the ~25 directly imaged planets to date, all are younger than 500Myr and all but 6 are younger than 100Myr. Eps Ind A (HD209100, HIP108870) is a K5V star of roughly solar age (r…
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…
The SOPHIE search for northern extrasolar planets-XIX. A system including a cold sub-Neptune potentially transiting a V = 6.5 star HD88986
N. Heidari, I. Boisse, N. C. Hara +51
Transiting planets with orbital periods longer than 40 d are extremely rare among the 5000+ planets discovered so far. The lack of discoveries of this population poses a challenge…
Multi techniques approach to identify and/or constrain radial velocity sub-stellar companions
F. Philipot, A. -M. Lagrange, F. Kiefer +3
Context. Although more than one thousand sub-stellar companions have already been detected with the radial velocity (RV) method, many new companions remain to be detected in the pu…
Preparing an unsupervised massive analysis of SPHERE high contrast data with the PACO algorithm
A. Chomez, A. -M. Lagrange, P. Delorme +9
We aim at searching for exoplanets on the whole ESO/VLT-SPHERE archive with improved and unsupervised data analysis algorithm that could allow to detect massive giant planets at 5…
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…
Updated characterization of long-period single companion by combining radial velocity, relative astrometry, and absolute astrometry
F. Philipot, A. -M. Lagrange, P. Rubini +2
Context. Thanks to more than 20 years of monitoring, the radial velocity (RV) method has detected long-period companions (P > 10yr) around several dozens of stars. Yet, the true na…
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…
