Constraining the size, shape, and albedo of the large Trans-Neptunian Object (28978) Ixion with multi-chord stellar occultations

Y. Kilic, F. Braga-Ribas, C. L. Pereira +81

Trans-Neptunian objects (TNOs) are among the most primitive remnants of the early Solar System, and constraining their sizes, shapes, albedos, and surface properties is essential f…

The rings of (2060) Chiron: Evidence of an evolving system

C. L. Pereira, F. Braga-Ribas, B. Sicardy +54

The centaur (2060) Chiron has long been a candidate for hosting material in orbit, based on occultation and photometric and spectroscopic data. Here, we present a multichord stella…

Asteroid sizes determined with thermophysical model and stellar occultations

A. Choukroun, A. Marciniak, J. Ďurech +165

Context. The sizes of many asteroids, especially slowly rotating, low-amplitude targets, remain poorly constrained due to selection effects. These biases limit the availability of…

Size and shape of the trans-Neptunian object (470316) 2007 OC10: Comparison with thermal data

J. M. Gómez-Limón, R. Leiva, J. L. Ortiz +40

The shapes of only 12 trans-Neptunian objects have been directly measured, offering crucial insights into their internal structure. These properties are strongly connected to the p…

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…

Physical properties of trans-Neptunian object (143707) 2003 UY117 derived from stellar occultation and photometric observations

M. Kretlow, J. L. Ortiz, J. Desmars +49

Trans-Neptunian objects (TNOs) are considered to be among the most primitive objects in our Solar System. Knowledge of their primary physical properties is essential for understand…
