Verification of photometric transformations for the LSST minor planet color data

Jiří Šilha, E. Lilly

Broadband color photometry of small Solar System bodies provides information about chemical, physical and structural properties of their surface material and helps to group them into different taxonomic classes, which give insights on their origin, physical and dynamical evolution. The recently commenced …

CO2-Driven Activity and Icy Coma Dust in the Active Centaur 450P/LONEOS

Charles Schambeau, Michael S. P. Kelley, Maria Womack, E. Lilly et autres

The Solar System’s Centaurs, sourced from trans-Neptunian object (TNOs) populations, contain some of the most primitive materials remaining from Solar System formation. They occupy dynamically unstable orbits between Neptune and Jupiter that generally evolve inward toward the Sun, with some eventually becoming …

Detection, Composition and Distribution of Ices on Outer Solar System Planetesimals by JWST

R. Brunetto, N. Pinilla-Alonso, John Stansberry, Sasha Cryan et autres

Trans-Neptunian objects (TNOs), Centaurs, and Neptune Trojans are relatively pristine remnants of the original Solar System planetesimals and therefore can inform us on planetary formation and evolution processes in the cold regions of our protoplanetary disk. Since 2022, using the James Webb …

JWST and Gemini Observations of the Active Centaur 450P/LONEOS: Nucleus and Coma Characterizations

Charles Schambeau, Michael S. P. Kelley, Maria Womack, E. Lilly et autres

Abstract Between 2019 and 2024, we used the Gemini-N and JWST observatories to conduct a detailed case study of the active Centaur 450P/LONEOS, whose orbit was significantly altered by a close Saturn encounter in 1992. Gemini-N Gemini Multi-Object Spectrograph optical images likely …

First results from the RENOIR survey: A Possible Evidence of Surface Transformation of Centaurs

E. Lilly, Charles Schambeau, Kathryn Volk, Peter Jevčák et autres

Centaurs are small bodies residing on unstable orbits between Jupiter and Neptune. As objects recently scattered from their sources in the Kuiper belt and beyond, they carry the compositional information of their parent populations into the realm of the giant planets. Unlike …

Verification of photometric transformations for small Solar System bodies on Main-Belt asteroid color data

V. I. Kuksenko, Peter Jevčák, Katarína Sabolová, Jiří Šilha et autres

The light reflected from the surface of solid celestial bodies like asteroids contains information about chemical composition, physical and structural properties of their near-surface material. Measurements of this reflected light through different broadband photometric filters enable us to study color properties of …

Exploring Dynamical and Evolutionary Processes via Debiased Main Belt Asteroid Size-Frequency Distributions

Sarah M. Sonnett, E. Lilly, T. Grav

Collisions, gravitational forces, and non-gravitational forces like YORP and Yarkovsky drift are three major processes that shape planetary systems. Due to their small sizes and lack of atmospheric weathering, asteroids are the most well-preserved tracers of these forces. The Main belt between …
