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…
The large Trans-Neptunian Object 2002 TC from combined stellar occultation, photometry and astrometry data
J. L. Ortiz, P. Santos-Sanz, B. Sicardy +78
On 28th January 2018, the large Trans-Neptunian Object (TNO) 2002TC302 occulted a m15.3 star with ID 130957813463146112 in the Gaia DR2 stellar catalog. 12 positive occultati…
The first observed stellar occultations by the irregular satellite (Saturn IX) Phoebe and improved rotational period
A. R. Gomes-Júnior, M. Assafin, F. Braga-Ribas +24
We report six stellar occultations by (Saturn IX) Phoebe, an irregular satellite of Saturn, obtained between mid-2017 and mid-2019. The 2017 July 06 event is the first stellar occu…
The 2014-2015 Brazilian Mutual Phenomena campaign for the Jovian satellites and improved results for the 2009 events
B. Morgado, R. Vieira-Martins, M. Assafin +15
Progress in astrometry and orbital modelling of planetary moons in the last decade enabled better determinations of their orbits. These studies need accurate positions spread over…
The trans-Neptunian object (84922) 2003 VS2 through stellar occultations
Gustavo Benedetti-Rossi, P. Santos-Sanz, J. L. Ortiz +50
We present results from three world-wide campaigns that resulted in the detections of two single-chord and one multi-chord stellar occultations by the Plutino object (84922) 2003~V…
First stellar occultation by the Galilean moon Europa and upcoming events between 2019 and 2021
B. Morgado, G. Benedetti-Rossi, A. R. Gomes-Júnior +21
Context. Bright stellar positions are now known with an uncertainty below 1 mas thanks to Gaia DR2. Between 2019-2020, the Galactic plane will be the background of Jupiter. The den…
