Refined physical parameters for Chariklo's body and rings from stellar occultations observed between 2013 and 2020

B. E. Morgado, B. Sicardy, F. Braga-Ribas +78

The Centaur (10199) Chariklo has the first rings system discovered around a small object. It was first observed using stellar occultation in 2013. Stellar occultations allow the de…

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…

Precise astrometry and diameters of asteroids from occultations -- a data-set of observations and their interpretation

David Herald, David Gault, Robert Anderson +10

Occultations of stars by asteroids have been observed since 1961, increasing from a very small number to now over 500 annually. We have created and regularly maintain a growing dat…

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…

Pluto's lower atmosphere and pressure evolution from ground-based stellar occultations, 1988-2016

E. Meza, B. Sicardy, M. Assafin +167

Context. Pluto's tenuous nitrogen (N2) atmosphere undergoes strong seasonal effects due to high obliquity and orbital eccentricity, and has been recently (July 2015) observed by th…

Size and shape of Chariklo from multi-epoch stellar occultations

R Leiva, B Sicardy, J I B Camargo +28

We use data from five stellar occultations observed between 2013 and 2016 to constrain Chariklo's size and shape, and the ring reflectivity. We consider four possible models for Ch…
