JWST occultation reveals unforeseen complexity in Chariklo's ring system
Pablo Santos-Sanz, Altair R. Gomes-Júnior, Bruno E. Morgado +25
Ring systems have been discovered around several small bodies in the outer Solar System through stellar occultations. While such measurements provide key information about ring geo…
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…
Beyond Point Masses. V. Weywot's Non-Keplerian Orbit
Benjamin Proudfoot, Will Grundy, Darin Ragozzine +1
We present a detailed dynamical analysis of the Quaoar-Weywot system based on nearly 20 years of high-precision astrometric data, including new HST observations and stellar occulta…
A high geometric albedo and small size of the Haumea cluster member (24835) 1995 SM55 from a stellar occultation and photometric observations
J. L. Ortiz, N. Morales, B. Sicardy +98
Trans-Neptunian objects (TNOs) are among the most ancient bodies of the solar system. Understanding their physical properties is key to constraining their origin and the evolution…
