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…

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…
