Binary asteroid candidates in Gaia DR3 astrometry
Luana Liberato, Paolo Tanga, David Mary +7
Asteroids with companions constitute an excellent sample for studying the collisional and dynamical evolution of minor planets. The currently known binary population were discovere…
Extending Lunar Impact Flash Observations into the Daytime with Short-Wave Infrared
Daniel Sheward, Marco Delbo, Chrysa Avdellidou +7
Lunar impact flash (LIF) observations typically occur in R, I, or unfiltered light, and are only possible during night, targeting the night side of a 10-60% illumination Moon, whil…

Aims. We aim to assess the suitability in the near-ultraviolet (NUV) region of the solar analogues selected by the team responsible for the asteroid reflectance included in Gaia Da…
Predictions for the Dynamical States of the Didymos System before and after the Planned DART Impact
Derek C. Richardson, Harrison F. Agrusa, Brent Barbee +33
NASA's Double Asteroid Redirection Test (DART) spacecraft is planned to impact the natural satellite of (65803) Didymos, Dimorphos, around 23:14 UTC on 26 September 2022, causing a…
Is 2021 PH27 an active asteroid with a meteor shower detectable on Venus?
Albino Carbognani, Paolo Tanga, Fabrizio Bernardi
The recently discovered near-Earth asteroid 2021 PH27 has the shortest orbital period of all known asteroids. It cannot be excluded that 2021 PH27 is also an active asteroid, as (3…
Asteroid astrometry by stellar occultations: Accuracy of the existing sample from orbital fitting
João F. Ferreira, Paolo Tanga, Federica Spoto +2
Context: Stellar occultations, greatly enhanced by the publication of the Gaia data releases, permit not only the determination of asteroid size and shape, but also the retrieval o…
An advanced multipole model for (216) Kleopatra triple system
M. Brož, F. Marchis, L. Jorda +37
To interpret adaptive-optics observations of (216) Kleopatra, we need to describe an evolution of multiple moons, orbiting an extremely irregular body and including their mutual in…
Evidence for differentiation of the most primitive small bodies
B. Carry, P. Vernazza, F. Vachier +40
Dynamical models of Solar System evolution have suggested that P-/D-type volatile-rich asteroids formed in the outer Solar System and may be genetically related to the Jupiter Troj…
A survey for occultation astrometry of Main Belt: expected astrometric performances
João F. Ferreira, Paolo Tanga, Pedro Machado +1
Context: Occultations of stars by asteroids are an efficient method to study the properties of minor bodies, and can be exploited as tools to derive very precise asteroid astrometr…
Binary asteroid (31) Euphrosyne: Ice-rich and nearly spherical
B. Yang, J. Hanus, B. Carry +38
Asteroid (31) Euphrosyne is one of the biggest objects in the asteroid main belt and the Euphrosyne family occupies a highly inclined region in the outer main belt and contains a r…
The role of fragment shapes in the simulations of asteroids as gravitational aggregates
Fabio Ferrari, Paolo Tanga
Remote measurements and in-situ observations confirm the idea that asteroids up to few hundreds of meters in size might be rubble piles. The dynamics of these objects can be studie…
The Geology and Geophysics of Kuiper Belt Object (486958) Arrokoth
J. R. Spencer, S. A. Stern, J. M. Moore +75
The Cold Classical Kuiper Belt, a class of small bodies in undisturbed orbits beyond Neptune, are primitive objects preserving information about Solar System formation. The New Hor…
Size and Shape Constraints of (486958) Arrokoth from Stellar Occultations
Marc W. Buie, Simon B. Porter, Peter Tamblyn +130
We present the results from four stellar occultations by (486958) Arrokoth, the flyby target of the New Horizons extended mission. Three of the four efforts led to positive detecti…
