Multi-epoch stellar occultations reveal Quaoar is an oblate spheroid with density 1.760±0.109 g/cm³, consistent with Maclaurin hydrostatic equilibrium and dwarf planet status.
Numerical integrations favor interpreting the Quaoar occultation feature as a satellite rather than a triangular-point confined arc, while identifying stable regions for additional moons.
Stellar occultation campaigns on Gaia binary candidates produced 33 multi-positive events for 24 asteroids, with four showing binary or contact-binary signatures.
N-body simulations show tidal fragments form narrow circular equatorial rings around Saturn for low-to-moderate inclinations with radius set by vertical angular momentum conservation, while high inclinations cause most material to accrete onto the planet.
The paper reports the design, commissioning on two runs, and measured performance of proto-Lightspeed, a seeing-limited high-speed imager delivering sub-electron read noise on the Magellan Clay Telescope.
The paper assesses the feasibility of using SKA-AA4 for thermal detections and characterization of TNOs and Centaurs at cm wavelengths.

A circumbinary approach to the study of spin-orbit resonances around irregular shaped bodies. Application to the Quaoar system
Replacing an irregular body by an equal-mass binary dumbbell converts its spin-orbit resonances into surrogate mean-motion resonances; for Quaoar the resulting maps show SORs play no relevant role in present ring dynamics.

Ring formation around giant planets by tidal disruption of a single passing large Kuiper belt object II: The dynamical fate of tidal fragments
N-body simulations show tidal fragments form narrow circular equatorial rings around Saturn for low-to-moderate inclinations with radius set by vertical angular momentum conservation, while high inclinations cause most material to accrete onto the planet.
