The spin state of asteroid Apophis and a prediction of its change during the 2029 close encounter with Earth
J. Durech, D. Vokrouhlicky, P. Pravec +23
On April 13, 2029, the asteroid Apophis will pass near Earth at a geocentric distance of about 38,000 km. Numerical models have suggested that the post-encounter spin state will cr…
Asteroid sizes determined with thermophysical model and stellar occultations
A. Choukroun, A. Marciniak, J. Ďurech +165
Context. The sizes of many asteroids, especially slowly rotating, low-amplitude targets, remain poorly constrained due to selection effects. These biases limit the availability of…
Asteroid phase curves and phase coloring effect using the ATLAS survey data
Colazo Milagros, Dagmara Oszkiewicz, Alvaro Alvarez-Candal +3
We determined phase curves for 301,272 asteroids in the orange filter and 280,953 in the cyan filter from the latest ATLAS Solar System Catalog V2 (SSCAT-2). Among them, 3,345 and…
Scaling slowly rotating asteroids by stellar occultations
A. Marciniak, J. Ďurech, A. Choukroun +176
As evidenced by recent survey results, majority of asteroids are slow rotators (P>12 h), but lack spin and shape models due to selection bias. This bias is skewing our overall unde…
The equilibrium shape of (65) Cybele: primordial or relic of a large impact?
M. Marsset, M. Brož, J. Vermersch +24
Cybele asteroids constitute an appealing reservoir of primitive material genetically linked to the outer Solar System, and the physical properties of the largest members can be rea…
Properties of slowly rotating asteroids from the Convex Inversion Thermophysical Model
A. Marciniak, J. Ďurech, V. Alí-Lagoa +73
Results from the TESS mission showed that previous studies strngly underestimated the number of slow rotators, revealing the importance of studying those asteroids. For most slowly…
(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…
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…
Thermal properties of slowly rotating asteroids: Results from a targeted survey
A. Marciniak, V. Alí-Lagoa, T. G. Müller +51
Context. Earlier work suggests that slowly rotating asteroids should have higher thermal inertias than faster rotators because the heat wave penetrates deeper into the sub-surface.…
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…
(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…
How the presence of a gas giant affects the formation of mean-motion resonances between two low-mass planets in a locally isothermal gaseous disc
Edyta Podlewska-Gaca, Ewa Szuszkiewicz
In this paper we investigate the possibility of a migration-induced resonance locking in systems containing three planets, namely an Earth analog, a super-Earth and a gas giant. Th…
Occurrence of the 2:1 commensurability in a gas giant-Super-Earth system
E. Podlewska-Gaca, E. Szuszkiewicz
We investigate how the conditions occurring in a protoplanetary disc may determine the final structure of a planetary system emerging from such a disc. We concentrate our attention…
Where can we find Super-Earths?
E. Podlewska-Gaca, E. Szuszkiewicz
In recent years we have been witnessing the discovery of one extrasolar gas giant after another. Now the time has come to detect more low-mass planets like Super-Earths and Earth-l…
