Centaur Nuclei: Sizes, Shapes, Spins, and Structure
We present a wide-ranging but in-depth analysis of Centaurs, focusing on their physical and structural aspects. Centaurs, originating from the Scattered Disk and Kuiper Belt, play a crucial role in our understanding of Solar System evolution. We first examine how biases in discovery and measurement affect our understanding of the Centaur size distribution. In particular we address the strong dependence of the census on perihelion distance and the broad distribution of Centaur geometric albedos.…

I thought that I've seen a centaur, but it turned out it was just a man with a shopping bag, walking a dog.

Scientist Use A.I. To Mimic the Mind, Warts and All
To better understand human cognition, scientists trained a large language model on 10 million psychology experiment questions. It now answers questions much like we do.

A foundation model to predict and capture human cognition - Nature
A computational model called Centaur, developed by fine-tuning a language model on a huge dataset called Psych-101, can predict and simulate human nature in experiments expressible in natural language, even in previously unseen situations.

The Near-Centaur Environment: Satellites, Rings, and Debris
The unexpected finding of a ring system around the Centaur (10199) Chariklo opened a new window for dynamical studies and posed many questions about the formation and evolutionary mechanisms of Centaurs as well as the relationship to satellites and outbursting activity. As minor planets that cross the orbits of the giant planets, Centaurs have short dynamical lifetimes: Centaurs are supplied from the trans-Neptunian region and some fraction migrates inward to become Jupiter-family comets. Given…

A minor planet in an outer resonance with Uranus
We have located archival observations of the centaur 2015 OU$_{194}$ from 2017 and 2018, which extend its data-arc length from 1.0 to 3.5 years. We show that it is in an outer $3:4$ mean motion resonance with Uranus, henceforth referred to as U$_{3/4}$. The resonance is stable from at least 1000 kyrs in the past till 500 kyrs in the future. We find no mention in the literature of known objects in this resonance, or in any other resonance between the orbits of Uranus and Neptune. Looking for add…
