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…
Size and Shape of Jupiter Trojan (2207) Antenor from Stellar Occultations
Feliphe S. Ferreira, Julio I. B. Camargo, Bruno E. Morgado +34
Librating around the Lagrange L5, the Jupiter's Trojan (2207) Antenor has been observed in recent years and its rotational light curve suggests it to be a very likely binary astero…
Stellar occultation observations of (38628) Huya and its satellite: a detailed look into the system
F. L. Rommel, E. Fernández-Valenzuela, B. C. N. Proudfoot +78
The physical and orbital parameters of Trans-Neptunian Objects (TNOs) provide valuable information about the Solar System's formation and evolution. In particular, the characteriza…
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 stellar occultation by (319) Leona on 13 September 2023 in preparation for the occultation of Betelgeuse
J. L. Ortiz, M. Kretlow, C. Schnabel +36
On 12 December 2023, the star Orionis (Betelgeuse) will be occulted by the asteroid (319) Leona. This represents an extraordinary and unique opportunity to analyze the diameter…
A large topographic feature on the surface of the trans-Neptunian object (307261) 2002 MS measured from stellar occultations
F. L. Rommel, F. Braga-Ribas, J. L. Ortiz +201
This work aims at constraining the size, shape, and geometric albedo of the dwarf planet candidate 2002 MS4 through the analysis of nine stellar occultation events. Using multichor…
Physical properties of the trans-Neptunian object (38628) Huya from a multi-chord stellar occultation
P. Santos-Sanz, J. L. Ortiz, B. Sicardy +85
Within our international program to obtain accurate physical properties of trans-Neptunian objects (TNOs) we predicted a stellar occultation by the TNO (38628) Huya of the star Gai…
The 2017 May 20 stellar occultation by the elongated centaur (95626) 2002 GZ
P. Santos-Sanz, J. L. Ortiz, B. Sicardy +56
We predicted a stellar occultation of the bright star Gaia DR1 4332852996360346368 (UCAC4 385-75921) (m= 14.0 mag) by the centaur 2002 GZ for 2017 May 20$^{\rm th}…
The large Trans-Neptunian Object 2002 TC from combined stellar occultation, photometry and astrometry data
J. L. Ortiz, P. Santos-Sanz, B. Sicardy +78
On 28th January 2018, the large Trans-Neptunian Object (TNO) 2002TC302 occulted a m15.3 star with ID 130957813463146112 in the Gaia DR2 stellar catalog. 12 positive occultati…
