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.…
High-precision astrometry and photometry with the JWST/MIRI imager
M. Libralato, I. Argyriou, D. Dicken +8
Astrometry is one of the main pillars of astronomy, and one of its oldest branches. Over the years, an increasing number of astrometric works by means of Hubble Space Telescope (HS…
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…
JWST MIRI flight performance: Detector Effects and Data Reduction Algorithms
Jane Morrison, Daniel Dicken, Ioannis Argyriou +21
The detectors in the Mid-Infrared Instrument (MIRI) of the James Webb Space Telescope (JWST) are arsenic-21 doped silicon impurity band conduction (Si:As IBC) devices and are direc…
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…
Geometric distortion and astrometric calibration of the JWST MIRI Medium Resolution Spectrometer
P. Patapis, I. Argyriou, D. R. Law +12
The Medium-Resolution integral field Spectrometer (MRS) of MIRI on board JWST performs spectroscopy between 5 and 28~m. The optics of the MRS introduce substantial distortion, a…
MINDS. Abundant water and varying C/O across the disk of Sz 98 as seen by JWST/MIRI
Danny Gasman, Ewine F. van Dishoeck, Sierra L. Grant +41
MIRI/MRS on board the JWST allows us to probe the inner regions of protoplanetary disks. Here we examine the disk around the classical T Tauri star Sz 98, which has an unusually la…
A 3D Drizzle Algorithm for JWST and Practical Application to the MIRI Medium Resolution Spectrometer
David R. Law, Jane E. Morrison, Ioannis Argyriou +4
We describe an algorithm for application of the classic `drizzle' technique to produce 3d spectral cubes using data obtained from the slicer-type integral field unit (IFU) spectrom…
A rich hydrocarbon chemistry and high C to O ratio in the inner disk around a very low-mass star
B. Tabone, G. Bettoni, E. F. van Dishoeck +43
Carbon is an essential element for life but how much can be delivered to young planets is still an open question. The chemical characterization of planet-forming disks is a crucial…
The James Webb Space Telescope Mission
Jonathan P. Gardner, John C. Mather, Randy Abbott +1004
Twenty-six years ago a small committee report, building on earlier studies, expounded a compelling and poetic vision for the future of astronomy, calling for an infrared-optimized…
The Brighter-Fatter Effect in the JWST MIRI Si:As IBC detectors I. Observations, impact on science, and modelling
Ioannis Argyriou, Craig Lage, George H. Rieke +10
The Mid-Infrared Instrument (MIRI) on board the James Webb Space Telescope (JWST) uses three Si:As impurity band conduction (IBC) detector arrays. The output voltage level of each…
JWST MIRI flight performance: The Medium-Resolution Spectrometer
Ioannis Argyriou, Alistair Glasse, David R. Law +22
The Medium-Resolution Spectrometer (MRS) provides one of the four operating modes of the Mid-Infrared Instrument (MIRI) on board the James Webb Space Telescope (JWST). The MRS is a…
Observations of the Planetary Nebula SMP LMC 058 with the JWST MIRI Medium Resolution Spectrometer
O. C. Jones, J. Álvarez-Márquez, G. C. Sloan +21
During the commissioning of {\em JWST}, the Medium-Resolution Spectrometer (MRS) on the Mid-Infrared Instrument (MIRI) observed the planetary nebula SMP LMC 058 in the Large Magell…
