Six transiting planets and a chain of Laplace resonances in TOI-178
Leleu, A.; Alibert, Y.; Hara, N. C.; Hooton, M. J.; Wilson, T. G.; Robutel, P.; Delisle, J. -B.; Laskar, J.; Hoyer, S.; Lovis, C.; Bryant, E. M.Determining the architecture of multi-planetary systems is one of the cornerstones of understanding planet formation and evolution. Resonant systems are especially important as the fragility of their orbital configuration ensures that no significant scattering or collisional event has taken place since the earliest formation phase when the parent protoplanetary disc was still present. In this context, TOI-178 h...
Stellar occultations enable milliarcsecond astrometry for Trans-Neptunian objec...
Rommel, F. L.; Braga-Ribas, F.; Desmars, J.; Camargo, J. I.B.; Ortiz, J. L.; Sicardy, B.; Vieira-Martins, R.; Assafin, M.; Santos-Sanz, P.; Duffard, R.Made available in DSpace on 2021-06-25T11:08:24Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-12-01; Context. 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...
