(216) Kleopatra, a low density critically rotating M-type asteroid
F. Marchis, L. Jorda, P. Vernazza +36
Context. The recent estimates of the 3D shape of the M/Xe-type triple asteroid system (216) Kleopatra indicated a density of 5 g.cm. Such a high density implies a high metal…
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…
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…
(704) Interamnia: A transitional object between a dwarf planet and a typical irregular-shaped minor body
J. Hanuš, P. Vernazza, M. Viikinkoski +56
With an estimated diameter in the 320 to 350 km range, (704) Interamnia is the fifth largest main belt asteroid and one of the few bodies that fills the gap in size between the fou…
The shape of (7) Iris as evidence of an ancient large impact?
J. Hanuš, M. Marsset, P. Vernazza +35
Asteroid (7) Iris is an ideal target for disk-resolved imaging owing to its brightness (V7-8) and large angular size of 0.33 arcsec during its apparitions. Iris is believed t…
Closing the gap between Earth-based and interplanetary mission observations: Vesta seen by VLT/SPHERE
R. JL. Fétick, L. Jorda, P. Vernazza +34
Context. Over the past decades, several interplanetary missions have studied small bodies in situ, leading to major advances in our understanding of their geological and geophysica…
The homogeneous internal structure of CM-like asteroid (41) Daphne
B. Carry, F. Vachier, J. Berthier +48
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 st…
(16) Psyche: A mesosiderite-like asteroid?
M. Viikinkoski, P. Vernazza, J. Hanus +35
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 woul…
Testing the inversion of asteroids' Gaia photometry combined with ground-based observations
T. Santana-Ros, P. Bartczak, T. Michałowski +2
We investigated the reliability of the genetic algorithm which will be used to invert the photometric measurements of asteroids collected by the European Space Agency Gaia mission.…
A new non-convex model of the binary asteroid 90 Antiope obtained with the SAGE modelling technique
P. Bartczak, T. Michałowski, T. Santana-Ros +1
We present a new non-convex model of the 90 Antiope binary asteroid, derived with a modified version of the SAGE (Shaping Asteroids with Genetic Evolution) method using disk-integr…
Asteroids' physical models from combined dense and sparse photometry and scaling of the YORP effect by the observed obliquity distribution
J. Hanuš, J. Ďurech, M. Brož +116
The larger number of models of asteroid shapes and their rotational states derived by the lightcurve inversion give us better insight into both the nature of individual objects and…
A Giant Crater on 90 Antiope?
P. Descamps, F. Marchis, T. Michalowski +11
Mutual event observations between the two components of 90 Antiope were carried out in 2007-2008. The pole position was refined to lambda0 = 199.5+/-0.5 eg and beta0 = 39.8+/-5 deg…
Observational detection of eight mutual eclipses and occultations between the satellites of Uranus
A. A. Christou, F. Lewis, P. Roche +13
We carried out observations, with five different instruments ranging in aperture from 0.4m to 10m, of the satellites of Uranus during that planet's 2007 Equinox. Our observations c…
