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…

A high geometric albedo and small size of the Haumea cluster member (24835) 1995 SM55 from a stellar occultation and photometric observations

J. L. Ortiz, N. Morales, B. Sicardy +98

Trans-Neptunian objects (TNOs) are among the most ancient bodies of the solar system. Understanding their physical properties is key to constraining their origin and the evolution…

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 size, shape, density and ring of the dwarf planet Haumea from a stellar occultation

J. L. Ortiz, P. Santos-Sanz, B. Sicardy +90

Among the four known transneptunian dwarf planets, Haumea is an exotic, very elongated, and fast rotating body. In contrast to the other dwarf planets, its size, shape, albedo, and…
