Near-Earth asteroid (NEA) 101955 (1999 RQ36; henceforth RQ36) is especially accessible to spacecraft and is the primary target of NASA's OSIRIS-REx sample...
Near-Earth asteroid (162173) 1999 JU3 (henceforth JU3) is a potentially hazardous asteroid and the target of the Japanese Aerospace Exploration Agency's...
The size distribution of asteroids in cometary orbits and related populations
Aims.In this work we study the cumulative size distribution of the population of asteroids in cometary orbits (ACOs), aiming to discriminate its cometary or...
The Splitting of Double-component Active Asteroid P/2016 J1 (PANSTARRS)
We present deep imaging observations, orbital dynamics, and dust-tail model analyses of the double-component asteroid P/2016 J1 (J1-A and J1-B). The...
The stellar occultation by (319) Leona on 2023 September 13 in preparation for the occultation of Betelgeuse
On 2023 December 12, the star α Orionis will be occulted by asteroid (319) Leona. This represents an extraordinary and unique opportunity to analyse the...
The TROY project. II. Multi-technique constraints on exotrojans in nine planetary systems
Context. Co-orbital bodies are the byproduct of planet formation and evolution, as we know from the solar system. Although planet-size co-orbitals do not exists...
The visible and near-infrared spectra of asteroids in cometary orbits
Context. Dynamical and albedo properties suggest that asteroids in cometary orbits (ACOs) are dormant or extinct comets. Their study provides new insights for...
Thermal properties of slowly rotating asteroids: results from a targeted survey
Context. Earlier work suggests that slowly rotating asteroids should have higher thermal inertias than faster rotators because the heat wave penetrates deeper...
Thermophysical properties of near-Earth asteroid (341843) 2008 EV5 from WISE data
Aims: We derive the thermal inertia of 2008 EV5, the baseline target for the Marco Polo-R mission proposal, and infer information about the size of the...
