Experimental test of a 40 cm-long R=100 000 spectrometer for exoplanet characterisation
Guillaume Bourdarot, Etienne Le Coarer, David Mouillet +12
High-resolution spectroscopy is a key element for present and future astronomical instrumentation. In particular, coupled to high contrast imagers and coronagraphs, high spectral r…
Discovery of a planetary-mass companion within the gap of the transition disk around PDS 70
M. Keppler, M. Benisty, A. Müller +123
Young circumstellar disks are of prime interest to understand the physical and chemical conditions under which planet formation takes place. Only very few detections of planet cand…
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…
Orbital and atmospheric characterization of the planet within the gap of the PDS 70 transition disk
A. Müller, M. Keppler, Th. Henning +43
Aims: We aim to characterize the orbital and atmospheric properties of PDS 70 b, which was first identified on May 2015 in the course of the SHINE survey with SPHERE, the extreme a…
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…
Orbital and spectral analysis of the benchmark brown dwarf HD 4747B
S. Peretti, D. Ségransan, B. Lavie +43
The study of high contrast imaged brown dwarfs and exoplanets depends strongly on evolutionary models. To estimate the mass of a directly imaged substellar object, its extracted ph…
