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…
JWST/NIRSpec Observations of Salacia-Actaea and Máni: Exploring Population-level Trends among Water-ice-rich Kuiper Belt Objects
Ian Wong, Bryan J. Holler, Silvia Protopapa +9
We present observations of the midsized Kuiper Belt objects (KBOs) SalaciaActaea and Máni, obtained with the Near-Infrared Spectrograph on JWST. The satellite Actaea was fully…
A few ideas to promote inclusion
Thibaut Paumard, Aurélie Guilbert-Lepoutre, Maïca Clavel +5
Promoting diversity, equity, inclusion and accessibility (DEIA) is both a legal and professional responsibility in French research institutions. This paper presents practical strat…
A portrait throughout perihelion of the NH-rich interstellar comet 2I/Borisov
Sophie E. Deam, Michele T. Bannister, Cyrielle Opitom +12
The interstellar comet 2I/Borisov is the first interstellar object where compositional characterisation was possible throughout its entire perihelion passage. We report all 16 epoc…
On the early thermal processing of planetesimals during and after the giant planet instability
A. Gkotsinas, D. Nesvorny, A. Guilbert-Lepoutre +2
Born as ice-rich planetesimals, cometary nuclei were gravitationally scattered onto their current orbits in the Kuiper Belt and the Oort Cloud during the giant planets' dynamical i…
