Trans-Neptunian objects (TNOs) and Centaurs are remnants of our planetary system formation, and their physical properties have invaluable information for evolutionary theories. Stellar occultation is a ground-based method for studying these distant small bodies and has presented exciting result...

Gomes, A. R. [UNESP]; Assafin, M.; Braga-Ribas, F.; Benedetti-Rossi, G.; Morgado, B. E.; Camargo, J. I.B.; Vieira-Martins, R.; Desmars, J.; Sicardy, B.Made available in DSpace on 2020-12-12T01:15:09Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-02-01; We report six stellar occultations by Phoebe (Saturn IX), an irregular satellite of Saturn, obtained between mid-2017 and mid-2019. The 2017 July 6 event was the first stellar occultation by an irregular satellite ever observed. The occultation chords were compared to a 3D shape model of the satellite o...
