Follow the wobble: Statistical methods to detect astrometric binary asteroids in Gaia FPR
Luana Liberato, Paolo Tanga, David Mary +7
In a previous article, we obtained the first-ever list of astrometric binary asteroid candidates. Some of these candidates have now been confirmed. In that previous work, however,…
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…
The Nysa family as the main source of unequilibrated LL ordinary chondrites
M. Marsset, P. Vernazza, M. Brož +16
Context. The origin of the petrologic diversity observed in ordinary chondrites (OCs), the most common meteorites on Earth, remains debated. Competing models invoke either depth-de…
Why the Northern Hemisphere Needs a 30-40m Telescope and the Science at Stake: from Interstellar Visitors to Planetary Defence
J. de León, N. Pinilla-Alonso, P. Tanga +49
Small Solar system Objects (SSOs) preserve the physical, chemical, and dynamical signatures of the Sun's protoplanetary disk. Upcoming surveys will discover vast numbers of new obj…
A dynamical dichotomy in large binary asteroids
K. Minker, B. Carry, F. Vachier +20
No less than 15% of large (diameter greater than 140 km) asteroids have satellites. The commonly accepted mechanism for their formation is post-impact reaccumulation. However, the…
Orbits of very distant asteroid satellites
K. Minker, B. Carry, F. Vachier +36
The very wide binary asteroid (VWBA) population is a small subset of the population of known binary and multiple asteroids made of systems with very widely orbiting satellites and…
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…
Binary craters on Ceres and Vesta and implications for binary asteroids
Carianna Herrera, Benoit Carry, Anthony Lagain +1
Context. Airless planetary objects have their surfaces covered by craters, and these can be used to study the characteristics of asteroid populations. Planetary surfaces present bi…
Gaia Focused Product Release: Sources from Service Interface Function image analysis -- Half a million new sources in omega Centauri
Gaia Collaboration, K. Weingrill, A. Mints +400
Gaia's readout window strategy is challenged by very dense fields in the sky. Therefore, in addition to standard Gaia observations, full Sky Mapper (SM) images were recorded for ni…
Gaia Focused Product Release: Radial velocity time series of long-period variables
Gaia Collaboration, M. Trabucchi, N. Mowlavi +403
The third Gaia Data Release (DR3) provided photometric time series of more than 2 million long-period variable (LPV) candidates. Anticipating the publication of full radial-velocit…
Euclid: Identification of asteroid streaks in simulated images using deep learning
M. Pöntinen, M. Granvik, A. A. Nucita +114
Up to 150000 asteroids will be visible in the images of the ESA Euclid space telescope, and the instruments of Euclid offer multiband visual to near-infrared photometry and slitles…
Close-to-fission dumbbell Jupiter-Trojan (17365) Thymbraeus
B. Carry, P. Descamps, M. Ferrais +11
Every population of small bodies in the Solar system contains a sizable fraction of multiple systems. Among these, the Jupiter Trojans have the lowest number of known binary system…
SsODNet: The Solar system Open Database Network
J. Berthier, B. Carry, M. Mahlke +1
The sample of Solar system objects has dramatically increased over the last decade. The amount of measured properties (e.g., diameter, taxonomy, rotation period, thermal inertia) h…
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…
Gaia Data Release 2: Mapping the Milky Way disc kinematics
Gaia Collaboration, D. Katz, T. Antoja +12
To illustrate the potential of GDR2, we provide a first look at the kinematics of the Milky Way disc, within a radius of several kiloparsecs around the Sun. We benefit for the firs…
GravityCam: Wide-Field High-Resolution High-Cadence Imaging Surveys in the Visible from the Ground
C. Mackay, M. Dominik, I. A. Steele +13
GravityCam is a new concept of ground-based imaging instrument capable of delivering significantly sharper images from the ground than is normally possible without adaptive optics.…
3D shape of asteroid (6)~Hebe from VLT/SPHERE imaging: Implications for the origin of ordinary H chondrites
