A Near-infrared Variability Survey of Young Planetary-mass Objects

Pengyu Liu, Beth A. Biller, Johanna M. Vos +12

We present a photometric variability survey of young planetary-mass objects using the New Technology Telescope in the Js and Ks bands. Surface gravity plays an important role in th…

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…

SO2, silicate clouds, but no CH4 detected in a warm Neptune

Achrene Dyrek, Michiel Min, Leen Decin +44

WASP-107b is a warm (~740 K) transiting planet with a Neptune-like mass of ~30.5 Earth masses and Jupiter-like radius of ~0.94 Jupiter radius, whose extended atmosphere is eroding.…

Imaging detection of the inner dust belt and the four exoplanets in the HR8799 system with JWST's MIRI coronagraph

Boccaletti A., Mâlin M., Baudoz P. +35

The multi planet system HR8799 is the first target observed with MIRI's coronagraphs as part of the MIRI-EC Guaranteed Time Observations exoplanets programme in Nov. 2022. We 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…

Retrieval study of cool, directly imaged exoplanet 51 Eri b

Niall Whiteford, Alistair Glasse, Katy L. Chubb +12

Retrieval methods are a powerful analysis technique for modelling exoplanetary atmospheres by estimating the bulk physical and chemical properties that combine in a forward model t…
