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…

Milliarcsecond astrometry for the Galilean moons using stellar occultations

B. E. Morgado, A. R. Gomes-Júnior, F. Braga-Ribas +40

A stellar occultation occurs when a Solar System object passes in front of a star for an observer. This technique allows the determination of sizes and shapes of the occulting body…

Stellar occultations enable milliarcsecond astrometry for Trans-Neptunian objects and Centaurs

F. L. Rommel, F. Braga-Ribas, J. Desmars +66

Trans-Neptunian objects (TNOs) and Centaurs are remnants of our planetary system formation, and their physical properties have invaluable information for evolutionary theories. Ste…

Spectroscopic Detection of the Pre-White Dwarf Companion of Regulus

Douglas R. Gies, Kathryn V. Lester, Luqian Wang +6

Mass transfer in an interacting binary will often strip the mass donor of its entire envelope and spin up the mass gainer to near critical rotation. The nearby B-type star Regulus…

Size and Shape Constraints of (486958) Arrokoth from Stellar Occultations

Marc W. Buie, Simon B. Porter, Peter Tamblyn +130

We present the results from four stellar occultations by (486958) Arrokoth, the flyby target of the New Horizons extended mission. Three of the four efforts led to positive detecti…

Results of two multi-chord stellar occultations by dwarf planet (1) Ceres

A. R. Gomes-Júnior, B. L. Giacchini, F. Braga-Ribas +24

We report the results of two multi-chord stellar occultations by the dwarf planet (1) Ceres that were observed from Brazil on 2010 August 17, and from the USA on 2013 October 25. F…
