FOSSIL. IV. The Significance-convergence Test—An Algorithm for Selecting Reliable Rotation Periods of Small Solar System Bodies Open
Manual review to select a reliable rotation period of small solar system bodies (SSSBs) is a very time-consuming process. With the growing volume of lightcurve data collected by wide-field, high-cadence surveys, such manual inspection has …

The Surfaces of Small to Midsize Plutinos: Evidence of an Association between Inclination and Surface Type Open
Being one of the most populated mean motion resonances (MMRs) with Neptune and lying close to the inner boundary of the present-day cold classical disk, observations of the orbital and surface class distributions of the plutinos in the 3:2…

Forcing Planets to Evolve: Interactions between Uranus and Neptune at Late Stages of Dynamical Evolution Open
In early solar system numerical simulations, where chaos is a primary driver, it is difficult to explore parameter space in a systematic way. In such simulations, stable configurations are hard to come by, and often require special fine-tu…

L<i>i</i>DO: Discovery of a 10:1 Resonator with a Novel Libration State Open
The Large inclination Distant Objects (L i DO) survey has discovered the first securely classified object in the 10:1 mean motion resonance of Neptune. This object, 2020 VN 40 , is short-term stable in the 10:1 resonance, but not stable on…

A Near-infrared Survey of Candidate Haumea Family Members Open
The Haumea family is the only known dynamical family in the trans-Neptunian region. To date, 10 family members have been unambiguously identified using near-infrared (NIR) spectral or photometric data in combination with their strong dynam…

Small Bodies in the Distant Solar System Open
The small bodies in the Kuiper Belt region of the distant Solar System are leftovers from planet formation. Their orbital distribution today tells us about how giant planets migrated, while their surface properties, shapes, and sizes tell …
