A roadmap for the atmospheric characterization of terrestrial exoplanets with JWST
TRAPPIST-1 JWST Community Initiative, :, Julien de Wit +80
Ultra-cool dwarf stars are abundant, long-lived, and uniquely suited to enable the atmospheric study of transiting terrestrial companions with JWST. Amongst them, the most prominen…
Near-Infrared Transmission Spectroscopy of HAT-P-18b with NIRISS: Disentangling Planetary and Stellar Features in the Era of JWST
Marylou Fournier-Tondreau, Ryan J. MacDonald, Michael Radica +24
The JWST Early Release Observations (ERO) included a NIRISS/SOSS (0.6-2.8m) transit of the 850K Saturn-mass exoplanet HAT-P-18b. Initial analysis of these data…
JWST transmission spectroscopy of HD 209458b: a super-solar metallicity, a very low C/O, and no evidence of CH4, HCN, or C2H2
Qiao Xue, Jacob L. Bean, Michael Zhang +3
We present the transmission spectrum of the original transiting hot Jupiter HD\,209458b from 2.3 -- 5.1 m as observed with the NIRCam instrument on the James Webb Space Telescop…
The distribution of CO on Europa indicates an internal source of carbon
Samantha K. Trumbo, Michael E. Brown
Jupiter's moon Europa has a subsurface ocean, the chemistry of which is largely unknown. Carbon dioxide (CO) has previously been detected on the surface of Europa, but it was n…
Atmospheric Reconnaissance of TRAPPIST-1 b with JWST/NIRISS: Evidence for Strong Stellar Contamination in the Transmission Spectra
Olivia Lim, Björn Benneke, René Doyon +22
TRAPPIST-1 is a nearby system of seven Earth-sized, temperate, rocky exoplanets transiting a Jupiter-sized M8.5V star, ideally suited for in-depth atmospheric studies. Each TRAPPIS…
Fitting the Light Curve of 1I/`Oumuamua with a Nonprincipal Axis Rotational Model and Outgassing Torques
Aster G. Taylor, Darryl Z. Seligman, Olivier R. Hainaut +1
In this paper, we investigate the nonprincipal axis (NPA) rotational state of 1I/`Oumuamua -- the first interstellar object discovered traversing the inner Solar System -- from its…
Moderate D/H Ratios in Methane Ice on Eris and Makemake as Evidence of Hydrothermal or Metamorphic Processes in Their Interiors: Geochemical Analysis
Christopher R. Glein, William M. Grundy, Jonathan I. Lunine +7
Dwarf planets Eris and Makemake have surfaces bearing methane ice of unknown origin. D/H ratios were recently determined from James Webb Space Telescope (JWST) observations of Eris…
The Spatial Distribution of the Unidentified 2.07 \textmu m Absorption Feature on Europa and Implications for its Origin
M. Ryleigh Davis, Michael E. Brown, Samantha K. Trumbo
A weak absorption feature at 2.07 \textmu m on Europa's trailing hemisphere has been suggested to arise from radiolytic processing of an endogenic salt, possibly sourced from the i…
Highly depleted alkali metals in Jupiter's deep atmosphere
Ananyo Bhattacharya, Cheng Li, Sushil K. Atreya +12
Water and ammonia vapors are known to be the major sources of spectral absorption at pressure levels observed by the microwave radiometer (MWR) on Juno. However, the brightness tem…
A Venus in the Making? Predictions for JWST Observations of the Ultracool M-Dwarf planet LP 890-9 c
Jonathan Gomez Barrientos, Lisa Kaltenegger, Ryan J. MacDonald
The recently discovered transiting super-Earth LP 890-9 c is potentially one of the best rocky exoplanets for atmospheric characterization. Orbiting an ultracool M-dwarf at the inn…
On the pollution of white dwarfs by exo-Oort cloud comets
Christopher E. O'Connor, Dong Lai, Darryl Z. Seligman
A large fraction of white dwarfs (WDs) have metal-polluted atmospheres, which are produced by accreting material from remnant planetary systems. The composition of the accreted deb…
BEAST detection of a brown dwarf and a low-mass stellar companion around the young bright B star HIP 81208
Gayathri Viswanath, Markus Janson, Raffaele Gratton +15
Recent observations from B-star Exoplanet Abundance Study (BEAST) have illustrated the existence of sub-stellar companions around very massive stars. In this paper, we present the…
A subsolar oxygen abundance or a radiative region deep in Jupiter revealed by thermochemical modelling
Thibault Cavalié, Jonathan Lunine, Olivier Mousis
Jupiter's deep abundances help to constrain the formation history of the planet and the environment of the protoplanetary nebula. Juno recently measured Jupiter's deep oxygen abund…
Mass Derivation of planets K2-21b and K2-21c from Transit Timing Variations
Maryame El Moutamid, Kevin B. Stevenson, Billy Quarles +5
While various indirect methods are used to detect exoplanets, one of the most effective and accurate methods is the transit method, which measures the brightness of a given star fo…
