Aims. Asteroid (31) Euphrosyne is one of the biggest objects in the asteroid main belt and it is also the largest member of its namesake family. The Euphrosyne family occupies a highly inclined region in the outer main belt and contains a remarkably large number of members, which is interpreted as an outcome of a disruptive cratering event. Methods. The goals of this adaptive-optics imaging study are threefold: to characterize the shape of Euphrosyne, to constrain its density, and to search for…

Physical and dynamical characterization of the Euphrosyne asteroid family

Aims. The Euphrosyne asteroid family occupies a unique zone in orbital element space around 3.15 au and may be an important source of the low-albedo near-Earth objects. The parent body of this family

Detection of a Satellite of the Trojan Asteroid (3548) Eurybates—A Lucy Mission Target

The discovery of a satellite of the Trojan asteroid Eurybates is described in images obtained with the Hubble Space Telescope and provides an opportunity for a significant expansion of the scientific return from this encounter.

Asteroid families: properties, recent advances, and future opportunities

Collisions are one of the key processes shaping planetary systems. Asteroid families are outcomes of such collision still identifiable across our solar system. The families provide a unique view of

Homogeneous internal structure of CM-like asteroid (41) Daphne

Context. CM-like asteroids (Ch and Cgh classes) are a major population within the broader C-complex, encompassing about 10% of the mass of the main asteroid belt. Their internal structure has been

(16) Psyche: A mesosiderite-like asteroid?

Context. Asteroid (16) Psyche is the target of the NASA Psyche mission. It is considered one of the few main-belt bodies that could be an exposed proto-planetary metallic core and that would thus be


The Euphrosyne asteroid family is uniquely situated at high inclination in the outer Main Belt, bisected by the &ngr; 6 ?> secular resonance. This large, low albedo family may thus be an important

The impact crater at the origin of the Julia family detected with VLT/SPHERE?

Context. The vast majority of the geophysical and geological constraints (e.g., internal structure, cratering history) for main-belt asteroids have so far been obtained via dedicated interplanetary

The violent collisional history of aqueously evolved (2) Pallas

Asteroid (2) Pallas is the largest main-belt object not yet visited by a spacecraft, making its surface geology largely unknown and limiting our understanding of its origin and collisional evolution.
