Distinguishing exoplanet companions from field stars in direct imaging using Gaia astrometry
Philipp Herz, Matthias Samland, Coryn A. L. Bailer-Jones
Direct imaging searches for exoplanets around stars detect many spurious candidates that are in fact background field stars. To help distinguish these from genuine companions, mult…
15NH3 in the atmosphere of a cool brown dwarf
David Barrado, Paul Mollière, Polychronis Patapis +40
Brown dwarfs serve as ideal laboratories for studying the atmospheres of giant exoplanets on wide orbits as the governing physical and chemical processes in them are nearly identic…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems III: Aperture Masking Interferometric Observations of the star HIP 65426 at 3.8 um
Shrishmoy Ray, Steph Sallum, Sasha Hinkley +121
We present aperture masking interferometry (AMI) observations of the star HIP 65426 at as a part of the JWST Direct Imaging Early Release Science (ERS) program obtai…
The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems IV: NIRISS Aperture Masking Interferometry Performance and Lessons Learned
Steph Sallum, Shrishmoy Ray, Jens Kammerer +120
We present a performance analysis for the aperture masking interferometry (AMI) mode on board the James Webb Space Telescope Near Infrared Imager and Slitless Spectrograph (JWST/NI…
The Chemical Inventory of the Inner Regions of Planet-forming Disks -- The JWST/MINDS Program
Inga Kamp, Thomas Henning, Aditya M. Arabhavi +40
The understanding of planet formation has changed recently, embracing the new idea of pebble accretion. This means that the influx of pebbles from the outer regions of planet-formi…
Water in the terrestrial planet-forming zone of the PDS 70 disk
G. Perotti, V. Christiaens, Th. Henning +42
Terrestrial and sub-Neptune planets are expected to form in the inner (AU) regions of protoplanetary disks. Water plays a key role in their formation, although it is yet uncl…
