Size, shape, density, and atmospheric limit of (50000) Quaoar revealed from 14 years of stellar occultation

Giuliano Margoti, Felipe Braga-Ribas, José Luis Ortiz +173

We present results from 28 stellar occultations by the large Trans-Neptunian Object (50000) Quaoar registered between 2018 and 2025. By performing a joint analysis of this occultat…

Detection and characterisation of binary asteroid candidates through stellar occultations

R. Lallemand, J. Desmars, B. Sicardy +256

Binary asteroids provide key access to fundamental parameters of Solar System remnants and planetary formations. However, the current knowledge of binary asteroids remains strongly…

A dynamical dichotomy in large binary asteroids

K. Minker, B. Carry, F. Vachier +20

No less than 15% of large (diameter greater than 140 km) asteroids have satellites. The commonly accepted mechanism for their formation is post-impact reaccumulation. However, the…

Orbits of very distant asteroid satellites

K. Minker, B. Carry, F. Vachier +36

The very wide binary asteroid (VWBA) population is a small subset of the population of known binary and multiple asteroids made of systems with very widely orbiting satellites and…

Investigating the formation of small Solar System objects using stellar occultations by satellites: present, future and its use to update satellite orbits

Felipe Braga-Ribas, Frederic Vachier, Josselin Desmars +2

The history of the outer solar system is intrinsically related to the Giant Planets migration. A massive disk of material within a radius of 30~au was scattered during the planetar…
