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…
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…
Kilometer-precise (UII) Umbriel physical properties from the multichord stellar occultation on 2020 September 21
M. Assafin, S. Santos-Filho, B. E. Morgado +39
We report the results of the stellar occultation by (UII) Umbriel on September 21st, 2020. The shadow crossed the USA and Canada, and 19 positive chords were obtained. A limb param…
The 2021 mutual phenomena involving the Galilean satellites of Jupiter and the inner satellite Thebe
L. M. Catani, M. Assafin, B. E. Morgado +7
Astrometric studies and orbital modeling of planetary moons have contributed significantly to advancing our understanding of their orbital dynamics. These studies require precise p…
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…
