Astrometric Accelerations as Dynamical Beacons: Discovery and Characterization of HIP 21152 B, the First T-Dwarf Companion in the Hyades
Kyle Franson, Brendan P. Bowler, Mariangela Bonavita +28
Benchmark brown dwarf companions with well-determined ages and model-independent masses are powerful tools to test substellar evolutionary models and probe the formation of giant p…
Stellar population of the Rosette Nebula and NGC 2244: application of the probabilistic random forest
Koraljka Muzic, Victor Almendros-Abad, Herve Bouy +5
(Abridged) In this work, we study the 2.8x2.6 deg2 region in the emblematic Rosette Nebula, centred at the young cluster NGC 2244, with the aim of constructing the most reliable ca…
Rogue planets and brown dwarfs: Predicting the populations of free-floating planetary mass objects observable with JWST
Aleks Scholz, Koraljka Muzic, Ray Jayawardhana +2
Free-floating (or rogue) planets are planets that are liberated (or ejected) from their host systems. Although simulations predict their existence in substantial numbers, direct ob…
Discovery of a brown dwarf with quasi-spherical mass-loss
Dary A. Ruíz-Rodríguez, Lucas A. Cieza, Simon Casassus +14
We report the serendipitous discovery of an elliptical shell of CO associated with the faint stellar object SSTc2d J163134.1-24006 as part of the "Ophiuchus Disk Survey Employing A…
Results from The COPAINS Pilot Survey: four new brown dwarfs and a high companion detection rate for accelerating stars
M. Bonavita, C. Fontanive, R. Gratton +6
The last decade of direct imaging (DI) searches for sub-stellar companions has uncovered a widely diverse sample that challenges the current formation models, while highlighting th…
The Near Infrared Imager and Slitless Spectrograph for the James Webb Space Telescope -- II. Wide Field Slitless Spectroscopy
Chris J. Willott, René Doyon, Loic Albert +26
We present the wide field slitless spectroscopy mode of the NIRISS instrument on the James Webb Space Telescope. This mode employs two orthogonal low-resolution (resolving power $\…
