Influence of the dynamic classification of asteroids on observation astrometric errors: a statistical analysis [PDF]

open access: yes, 2023
The ephemerides of minor planets are computed on the basis of astrometric observations. The asteroid orbit determination process requires these observations to be properly weighted to take into account the expected accuracy of the data.

Rotation periods and shape asphericity in asteroid families based on TESS S1-S13 observations [PDF]

open access: yes, 2022
Here we present the analysis of the distribution of rotation periods and light curve amplitudes based on 2859 family asteroids in 16 Main Belt families based on 9912 TESS asteroid light curves in the TSSYS-DR1 asteroid light curve database. We found that

Chaotic diffusion caused by close encounters with several massive asteroids: II. the regions of (10) Hygiea, (2) Pallas, and (31) Euphrosyne [PDF]

open access: yes, 2013
Context. Close encounters with (1) Ceres and (4) Vesta, the two most massive bodies in the main belt, are known to be a mechanism of dynamical mobility able to significantly alter proper elements of minor bodies, and they are the main source of dynamical

Euclid: Identification of asteroid streaks in simulated images using deep learning

open access: yes, 2023
The material composition of asteroids is an essential piece of knowledge in the quest to understand the formation and evolution of the Solar System. Visual to near-infrared spectra or multiband photometry is required to constrain the material composition

Can Asteroid Belts Exist in the Luyten’s System?

open access: yes, 2022
The extra-solar planetary system Luyten is relatively close (12.3 light years) to our Sun. The Luyten’s red dwarf star is orbited by four planets, two of them Earth-like (in mass) and in 4:1 resonance.

Statistical and Numerical Study of Asteroid Orbital Uncertainty [PDF]

open access: yes, 2013
Context. The knowledge of the orbit or the ephemeris uncertainty of asteroid presents a particular interest for various purposes. These quantities are for instance useful for recovering asteroids, for identifying lost asteroids or for planning stellar ...

Geomorphology and structural geology of Saturnalia Fossae and adjacent structures in the northern hemisphere of Vesta [PDF]

open access: yes, 2014
: Vesta is a unique, intermediate class of rocky body in the Solar System, between terrestrial planets and small asteroids, because of its size (average radius of ∼263 km) and differentiation, with a crust, mantle and core. Vesta’s low surface gravity (0.

Visible spectroscopy from the Mission Accessible Near-Earth Object Survey (MANOS): taxonomic dependence on asteroid size

open access: yes, 2020
The Mission Accessible Near-Earth Object Survey (MANOS) aims to observe and characterize small (mean absolute magnitude H ~ 25 mag) Near-Earth Objects (NEOs) that are accessible by spacecraft (mean Δv ~ 5.7 km s−1) and that make close approaches with the

PHOTOMETRIC OBSERVATIONS CONSTRAINING THE SIZE, SHAPE, AND ALBEDO OF 2003 EL61, A RAPIDLY ROTATING, PLUTO-SIZED OBJECT IN THE KUIPER BELT [PDF]

open access: yes, 2005
We present measurements at optical wavelengths of the spectral reflectance, rotational light curve, and solar phase curve of 2003 EL61. With apparent visual magnitude 17.5 at 51 AU from the Sun, this newly discovered member of the classical Kuiper Belt ...
