Spectral and orbital characterisation of the directly imaged giant planet HIP 65426 b
A. C. Cheetham, M. Samland, S. S. Brems +38
HIP 65426 b is a recently discovered exoplanet imaged during the course of the SPHERE-SHINE survey. Here we present new and observations of the planet from the NACO instr…
The limit of the gyrochronology - A new age determination technique: the tidal-chronology
Florian Gallet, Philippe Delorme
While the number of detected planets is continuously increasing since 1995, their impact on their central star still remain poorly understood. Yet, the presence of a massive close-…
WEIRD: Wide-orbit Exoplanet search with InfraRed Direct imaging
Frédérique Baron, Étienne Artigau, Julien Rameau +9
We report results from the Wide-orbit Exoplanet search with InfraRed Direct imaging (WEIRD), a survey designed to search for Jupiter-like companions on very wide orbits (1000 to 50…
The GJ 504 system revisited. Combining interferometric, radial velocity, and high contrast imaging data
M. Bonnefoy, K. Perraut, A. -M. Lagrange +79
The G-type star GJ504A is known to host a 3 to 35 MJup companion whose temperature, mass, and projected separation all contribute to make it a test case for the planet formation th…
Dynamical masses of M-dwarf binaries in young moving groups: I - The case of TWA 22 and GJ 2060
L. Rodet, M. Bonnefoy, S. Durkan +48
Evolutionary models are widely used to infer the mass of stars, brown dwarfs, and giant planets. Their predictions are thought to be less reliable at young ages ( 200 Myr) and i…
Astrometric and photometric accuracies in high contrast imaging: The SPHERE speckle calibration tool (SpeCal)
R. Galicher, A. Boccaletti, D. Mesa +21
The consortium of the Spectro-Polarimetric High-contrast Exoplanet REsearch installed at the Very Large Telescope (SPHERE/VLT) has been operating its guaranteed observation time (2…
