JWST reveals anomalously enhanced methane outgassing from below Chiron's water ice and carbon dioxide bearing surface

Ian Wong, Silvia Protopapa, Aurélie Guilbert-Lepoutre +7

Centaurs are inward-scattered Kuiper belt objects, with some exhibiting comet-like activity. The physical mechanisms powering this activity remain poorly understood, with carbon mo…

Surface properties of large TNOs: Expanding the study to longer wavelengths with the James Webb Space Telescope

Noemí Pinilla-Alonso, John Stansberry, Bryan Holler

The largest trans-Neptunian objects (TNOs) represent an extremely diverse collection of primitive bodies in the outer solar system. The community typically refers to these objects…

JWST Observations of Asteroid 2024 YR4 Rule Out a 2032 Lunar Impact and Demonstrate a New Regime for Planetary Defense Follow-up

Julien de Wit, Andrew S. Rivkin, Marco Micheli +12

At the end of its discovery apparition, the 60 m near-Earth object 2024 YR4 was associated with a non-zero probability of lunar impact during its 2032 December 22 close appro…

Compositional characterisation of asteroid (84) Klio with JWST

Tania Le Pivert-Jolivet, Julia de León, Javier Licandro +8

The analysis of the composition of primitive Ccomplex asteroids is essential to understand the distribution of volatiles in the Solar System since its formation. Primitive low-a…

Constraints on Quaoar's rings and atmosphere from JWST/NIRCam observations of a stellar occultation

Benjamin Proudfoot, Bryan Holler, Ko Arimatsu +3

Observations of stellar occultations have revealed that small bodies are capable of hosting ring systems. The trans-Neptunian object (TNO) Quaoar, is the host of an enigmatic ring…

Exploring the composition of icy bodies at the fringes of the Solar System with next generation space telescopes

Richard J. Cartwright, Bryan Holler, Susan Benecchi +4

Determining the distribution and spectral signature of volatile ices and organics exposed on icy body surfaces can provide crucial clues for deciphering how the outer solar system…
