Size, shape, density, and atmospheric limit of (50000) Quaoar revealed from 14 years of stellar occultation
Giuliano Margoti, Felipe Braga-Ribas, José Luis Ortiz +173
We present results from 28 stellar occultations by the large Trans-Neptunian Object (50000) Quaoar registered between 2018 and 2025. By performing a joint analysis of this occultat…
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…
Catastrophic disruption of asteroid 2023 CX1 and implications for planetary defense
Auriane Egal, Denis Vida, François Colas +94
Mitigation of the threat from airbursting asteroids requires an understanding of the potential risk they pose for the ground. How asteroids release their kinetic energy in the atmo…
The Ongoing Decline in Activity of Comet 103P/Hartley 2
Ariel Graykowski, Guillaume Langin, David Chiron +102
We report photometric observations of Comet 103P/Hartley 2 during its 2023 apparition. Our campaign, conducted from August through December 2023, combined data from a global networ…
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…
The Gaia-FUN-SSO observation campaign of 99942 Apophis: A preliminary test for the network
D. Bancelin, W. Thuillot, A. Ivantsov +8
In order to test the coordination and evaluate the overall performance of the Gaia-FUN-SSO, an observation campaign on the Potentially Hazardous Asteroid (99 942) Apophis was condu…
Orbit determination of Transneptunian objects and Centaurs for the prediction of stellar occultations
J. Desmars, J. I. B. Camargo, F. Braga-Ribas +10
The prediction of stellar occultations by Transneptunian objects and Centaurs is a difficult challenge that requires accuracy both in the occulted star position as for the object e…
