Redshifting the Study of Cold Brown Dwarfs and Exoplanets: the Mid-Infrared Wavelength Region as an Indicator of Surface Gravity and Mass
S. K. Leggett, Pascal Tremblin
JWST is opening many avenues for exploration. For cold brown dwarfs and exoplanets, JWST has opened the door to the mid-infrared wavelength region, where such objects emit signific…
Water depletion and 15NH3 in the atmosphere of the coldest brown dwarf observed with JWST/MIRI
H. Kühnle, P. Patapis, P. Mollière +21
With a temperature of K WISE0855 is the coldest brown dwarf observed so far. Using the James Webb Space Telescope (JWST) we obtained observations that allow us to charac…
JWST/NIRSpec Observations of Brown Dwarfs in the Orion Nebula Cluster
K. L. Luhman, C Alves de Oliveira, I. Baraffe +4
We have used the multiobject mode of the Near-Infrared Spectrograph (NIRSpec) on board the James Webb Space Telescope (JWST) to obtain low-resolution 1-5um spectra of 22 brown dwar…
A new atmospheric characterization of the sub-stellar companion HR\,2562\,B with JWST/MIRI observations
Nicolás Godoy, Elodie Choquet, Eugene Serabyn +8
Context: HR2562B is a planetary-mass companion located 0.56arcsec (19au) from its host star. It is one of a few L/T transitional objects orbiting a young star. This companion provi…
Reevaluating the cosmological redshift: insights into inhomogeneities and irreversible processes
P. Tremblin, G. Chabrier
Understanding the expansion of the Universe remains a profound challenge in fundamental physics. The complexity of solving General Relativity equations in the presence of intricate…
The JWST Weather Report from the Nearest Brown Dwarfs I: multi-period JWST NIRSpec + MIRI monitoring of the benchmark binary brown dwarf WISE 1049AB
Beth A. Biller, Johanna M. Vos, Yifan Zhou +22
We report results from 8 hours of JWST/MIRI LRS spectroscopic monitoring directly followed by 7 hours of JWST/NIRSpec prism spectroscopic monitoring of the benchmark binary brown d…
