KRONOS I: The m JWST Transmission Spectrum of the 23 Myr V1298 Tau c
Matthew M. Murphy, Matthew C. Nixon, Adina D. Feinstein +16
While recent JWST observations of mature super-Earths and sub-Neptunes have frequently revealed featureless transmission spectra, their inflated progenitors offer a unique window i…
An Assessment of Organics Detection and Characterization on the Surface of Europa with Infrared Spectroscopy
Ishan Mishra, Nikole Lewis, Jonathan Lunine +1
Organics, if they do exist on Europa, may only be present in trace amounts on the surface. NASA's upcoming mission Europa Clipper is going to provide global, high quality data of t…
Uranus Study Report: KISS
Mark Hofstadter, Ravit Helled, David J. Stevenson +27
Determining the internal structure of Uranus is a key objective for planetary science. Knowledge of Uranus's bulk composition and the distribution of elements is crucial to underst…
Retrievals on NIRCam transmission and emission spectra of HD 189733b with PLATON 6, a GPU code for the JWST era
Michael Zhang, Kimberly Paragas, Jacob L. Bean +5
We present the 2.4--5.0 \um JWST/NIRCam emission spectrum of HD 189733b, along with an independent re-reduction of the previously published transmission spectrum at the same wavele…
A broad set of solar and cosmochemical data indicates high C-N-O abundances for the solar system
Ngoc Truong, Christopher R. Glein, Jonathan I. Lunine
We examine the role of refractory organics as a major C carrier in the outer protosolar nebula and its implications for the compositions of large Kuiper belt objects (KBOs) and CI…
JWST Thermal Emission of the Terrestrial Exoplanet GJ 1132b
Qiao Xue, Jacob L. Bean, Michael Zhang +9
We present thermal emission measurements of GJ 1132b spanning 5--12 um obtained with the Mid-Infrared Instrument Low-Resolution Spectrometer (MIRI/LRS) on the James Webb Space Tele…
The deep oxygen abundance in Solar System Giant Planets, with a new derivation for Saturn
Thibault Cavalié, Jonathan Lunine, Olivier Mousis +1
Deep elemental composition is a challenging measurement to achieve in the giant planets of the solar system. Yet, knowledge of the deep composition offers important insights in the…
Insights on the Formation Conditions of Uranus and Neptune from their Deep Elemental Compositions
Olivier Mousis, Antoine Schneeberger, Thibault Cavalié +6
This study, placed in the context of the preparation for the Uranus Orbiter Probe mission, aims to predict the bulk volatile compositions of Uranus and Neptune. Using a protoplanet…
Recipes for forming a carbon-rich giant planet
Olivier Mousis, Thibault Cavalié, Jonathan I. Lunine +9
The exploration of carbon-to-oxygen ratios has yielded intriguing insights into the composition of close-in giant exoplanets, giving rise to a distinct classification: carbon-rich…
Formation of the Trappist-1 system in a dry protoplanetary disk
Antoine Schneeberger, Olivier Mousis, Magali Deleuil +1
A key feature of the Trappist-1 system is its monotonic decrease in bulk density with growing distance from the central star, which indicates an ice mass fraction that is zero in t…
A Combined Ground-based and JWST Atmospheric Retrieval Analysis: Both IGRINS and NIRSpec Agree The Atmosphere of WASP-77A b is Metal-Poor
Peter Smith, Michael Line, Jacob Bean +12
Ground-based, high-resolution and space-based, low-resolution spectroscopy are the two main avenues through which transiting exoplanet atmospheres are studied. Both methods provide…
On the hypothesis of an inverted Z-gradient inside Jupiter
Saburo Howard, Tristan Guillot, Steve Markham +6
Models of Jupiter s interior struggle to agree with measurements of the atmospheric composition. Interior models favour a subsolar or solar abundance of heavy elements Z while atmo…
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…
Airfall on Comet 67P/Churyumov-Gerasimenko
B. J. R. Davidsson, S. Birch, G. A. Blake +11
We here study the transfer process of material from one hemisphere to the other (deposition of airfall material) on an active comet nucleus, specifically 67P/Churyumov-Gerasimenko.…
Evidence for multiple Ferrel-like cells on Jupiter
Keren Duer, Nimrod Gavriel, Eli Galanti +14
Jupiter's atmosphere is dominated by multiple jet streams which are strongly tied to its 3D atmospheric circulation. Lacking a rigid bottom boundary, several models exist for how t…
Comparing key compositional indicators in Jupiter with those in extra-solar giant planets
J. I. Lunine, T. Greene, C. Beichman +3
Spectroscopic transiting observations of the atmospheres of hot Jupiters around other stars, first with Hubble Space Telescope and then Spitzer, opened the door to compositional st…
Stability of sulphur dimers S2 in cometary ices
O. Mousis, O. Ozgurel, J. I. Lunine +5
S2 has been observed for decades in comets, including comet 67P/Churyumov-Gerasimenko. Despite the fact that this molecule appears ubiquitous in these bodies, the nature of its sou…
Possible Internal Structures and Compositions of Proxima Centauri b
B. Brugger, O. Mousis, M. Deleuil +1
We explore the possible Proxima Centauri b's interiors assuming the planet belongs to the class of dense solid planets (rocky with possible addition of water) and derive the corres…
