We present the highest fidelity spectrum to date of a planetary-mass object. VHS 1256 b is a 20 M widely separated (8\arcsec, a = 150 au), young, planetary-…
Updated orbital monitoring and dynamical masses for nearby M-dwarf binaries
Per Calissendorff, Markus Janson, Laetitia Rodet +26
Young M-type binaries are particularly useful for precise isochronal dating by taking advantage of their extended pre-main sequence evolution. Orbital monitoring of these low-mass…
A Novel Survey for Young Substellar Objects with the W band Filter.V. IC 348 and Barnard 5 in the Perseus Cloud
Bhavana Lalchand, Wen-Ping Chen, Beth A. Biller +10
We report the discovery of substellar objects in the young star cluster IC 348 and the neighboring Barnard 5 dark cloud, both at the eastern end of the Perseus star-forming complex…
Reference-star differential imaging on SPHERE/IRDIS
Chen Xie, Elodie Choquet, Arthur Vigan +14
Reference-star differential imaging (RDI) is a promising technique in high-contrast imaging that is thought to be more sensitive to exoplanets and disks than angular differential i…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems I: High Contrast Imaging of the Exoplanet HIP 65426 b from 2-16 m
Aarynn L. Carter, Sasha Hinkley, Jens Kammerer +108
We present JWST Early Release Science (ERS) coronagraphic observations of the super-Jupiter exoplanet, HIP 65426 b, with the Near-Infrared Camera (NIRCam) from 2-5 m, and with t…
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…
