(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…
Seasonal Mass Transfer on the Nucleus of Comet 67P/Chuyumov-Gerasimenko
H. U. Keller, S. Mottola, S. F. Hviid +47
We collect observational evidence that supports the scheme of mass transfer on the nucleus of comet 67P/Churyumov-Gerasimenko. The obliquity of the rotation axis of 67P causes stro…
Different origins or different evolutions? Decoding the spectral diversity among C-type asteroids
P. Vernazza, J. Castillo-Rogez, P. Beck +15
Anhydrous pyroxene-rich interplanetary dust particles (IDPs) have been proposed as surface analogs for about two-thirds of all C-complex asteroids. However, this suggestion appears…
Similar origin for low- and high-albedo Jovian Trojans and Hilda asteroids ?
Michaël Marsset, Pierre Vernazza, Florian Gourgeot +4
Hilda asteroids and Jupiter Trojans are two low-albedo (p ~ 0.07) populations for which the Nice model predicts an origin in the primordial Kuiper Belt region. However, r…
The Cratering History of Asteroid (2867) Steins
S. Marchi, C. Barbieri, M. Kueppers +8
The cratering history of main belt asteroid (2867) Steins has been investigated using OSIRIS imagery acquired during the Rosetta flyby that took place on the 5th of September 2008.…
