Detection and characterisation of binary asteroid candidates through stellar occultations
R. Lallemand, J. Desmars, B. Sicardy +256
Binary asteroids provide key access to fundamental parameters of Solar System remnants and planetary formations. However, the current knowledge of binary asteroids remains strongly…
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,…
A practical re-weighting scheme of data fitting: application to asteroids orbit determination with Gaia
Dmitri. E. Vavilov, Ziyu. Liu, Daniel. Hestroffer +1
The method of weighted least squares is widely used in parameter estimation problems such as asteroid orbit determination. A key difficulty is the treatment of observational uncert…
NEOForCE: Near-Earth Objects' Forecast of Collisional Events
Dmitrii E. Vavilov, Daniel Hestroffer
Robust impact monitoring of near-Earth objects is an essential task of planetary defense. Current systems such as NASA's Sentry-II, the University of Pisa's CLOMON2, and ESA's Aegi…
Asteroid (4337) Arecibo: Two ice-rich bodies forming a binary -- Based on Gaia astrometric data
Ziyu Liu, Daniel Hestroffer, Josselin Desmars +1
Context. Binary asteroids are present in all populations of the Solar System, from near-Earth to trans-Neptunian regions. As is true for the small Solar System bodies (SSSBs), bina…
Ground-based astrometry calibrated by Gaia DR1: new perspectives in asteroid orbit determination
F. Spoto, P. Tanga, S. Bouquillon +10
The Gaia Data Release 1 (GDR1) is a first, important step on the path of evolution of astrometric accuracy towards a much improved situation. Although asteroids are not present in…
