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…
Prediction and observation of a stellar occultation by Haumea's satellite Namaka
F. L. Rommel, B. C. N. Proudfoot, B. J. Holler +2
Stellar occultations are an ideal way to characterize the physical and orbital properties of trans-Neptunian binary systems. In this research note, we detail the prediction and obs…
Physical Characteristics of Jupiter's Trojan (1437) Diomedes from a Tri-chord Stellar Occultation in 2020 and Dimensionless 3D Model
H. Dutra, M. Assafin, B. Sicardy +15
Jupiter Trojans preserve primitive formation characteristics due to their collisionless stable orbits. Determination of their shapes and size-frequency distribution constrains the…
Centaur 29P/Schwassmann-Wachmann 1 and its near-nucleus environment from a stellar occultation
C. L. Pereira, F. Braga-Ribas, B. Sicardy +9
Comets offer valuable insights into the early Solar System's conditions and processes. Stellar occultations enables detailed study of cometary nuclei typically hidden by their coma…
Stellar occultations by Trans-Neptunian Objects
Bruno Sicardy, Felipe Braga-Ribas, Marc W. Buie +2
Stellar occultations provide a powerful tool to explore objects of the outer solar system. The Gaia mission now provides milli-arcsec accuracy on the predictions of these events an…
Prominent mid-infrared excess of the dwarf planet (136472) Makemake discovered by JWST/MIRI indicates ongoing activity
Csaba Kiss, Thomas G. Müller, Anikó Farkas-Takács +18
We report on the discovery of a very prominent mid-infrared (18-25 μm) excess associated with the trans-Neptunian dwarf planet (136472) Makemake. The excess, detected by the MIRI i…
Constraints on Triton atmospheric evolution from occultations: 1989-2022
B. Sicardy, A. Tej, A. R. Gomes-Junior +49
Context - Around the year 2000, Triton's south pole experienced an extreme summer solstice that occurs every about 650 years, when the subsolar latitude reached about 50°. Bracketi…
