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…
HD 7977 and its possible influence on Solar System bodies
Piotr A. Dybczyński, Małgorzata Królikowska, Przemysław Bartczak +5
In the latest Gaia third data release one can find extremely small proper motion components for the star HD 7977. This, together with the radial velocity measurement lead to the co…

Piotr A. Dybczyński, Filip Berski, Jakub Tokarek +3
Context. In 2020, the initial version of the Stellar Potential Perturbers Database (StePPeD) was presented with the aim to deliver up-to-date information on the stars and stellar s…
(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…
Determination of rotation periods for a large sample of asteroids from K2 Campaign 9
Edyta Podlewska-Gaca, Radosław Poleski, Przemysław Bartczak +2
Kepler mission is a powerful tool in the study the different types of astrophysical objects or events in the distant Universe. However, the spacecraft gives also the opportunity to…
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…
The size, shape, density and ring of the dwarf planet Haumea from a stellar occultation
J. L. Ortiz, P. Santos-Sanz, B. Sicardy +90
Among the four known transneptunian dwarf planets, Haumea is an exotic, very elongated, and fast rotating body. In contrast to the other dwarf planets, its size, shape, albedo, and…
The large Trans-Neptunian Object 2002 TC from combined stellar occultation, photometry and astrometry data
J. L. Ortiz, P. Santos-Sanz, B. Sicardy +78
On 28th January 2018, the large Trans-Neptunian Object (TNO) 2002TC302 occulted a m15.3 star with ID 130957813463146112 in the Gaia DR2 stellar catalog. 12 positive occultati…
Thermal properties of large main-belt asteroids observed by Herschel PACS
V. Alí-Lagoa, T. G. Müller, C. Kiss +11
Non-resolved thermal infrared observations enable studies of thermal and physical properties of asteroid surfaces provided the shape and rotational properties of the target are wel…
Physical parameters of selected Gaia mass asteroids
E. Podlewska-Gaca, A. Marciniak, V. Alí-Lagoa +36
Thanks to the Gaia mission, it will be possible to determine the masses of approximately hundreds of large main belt asteroids with very good precision. We currently have diameter…
(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…
A new non-convex model of the binary asteroid (809) Lundia obtained with the SAGE modelling technique
P. Bartczak, A. Kryszczyńska, G. Dudziński +12
We present a new non-convex model of the binary asteroid (809) Lundia. A SAGE (Shaping Asteroids with Genetic Evolution) method using disc-integrated photometry only was used for d…
Volume uncertainty assessment method of asteroid models from disk-integrated visual photometry
P. Bartczak, G. Dudziński
The need for more accurate asteroid models is perhaps secondary to the need to measure their quality. The uncertainties of models' parameters propagate to quantities like volume or…
