Unmasking (44) Nysa: Evidence for a trilobate structure
Kate Minker, Anthony Berdeu, Gianluca Li Causi +16
Context. (44) Nysa is one of the largest known E-type asteroids. Light curve inversion models have indicated that it may have an elongated shape commonly found in large binary syst…
Follow the wobble: Statistical methods to detect astrometric binary asteroids in Gaia FPR
Luana Liberato, Paolo Tanga, David Mary +7
In a previous article, we obtained the first-ever list of astrometric binary asteroid candidates. Some of these candidates have now been confirmed. In that previous work, however,…
The Nysa family as the main source of unequilibrated LL ordinary chondrites
M. Marsset, P. Vernazza, M. Brož +16
Context. The origin of the petrologic diversity observed in ordinary chondrites (OCs), the most common meteorites on Earth, remains debated. Competing models invoke either depth-de…
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…
On inertial forces (indirect terms) in problems with a central body
Aurélien Crida, Clément Baruteau, Philippine Griveaud +14
Gravitational systems in astrophysics often comprise a body -- the primary -- that far outweights the others, and which is taken as the centre of the reference frame. A fictitious…
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…
