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…

Constraining the nature of the possible extrasolar PDS110b ring system

Tiago F. L. L. Pinheiro, Rafael Sfair

The young star PDS110 in the Ori OB1a association underwent two similar eclipses in 2008 and 2011, each of which lasted for a period of at least 25 days. One plausible explanation…

Stability and Evolution of Fallen Particles Around the Surface of Asteroid (101955) Bennu

A. Amarante, O. C. Winter, R. Sfair

In this work, we study the dynamics of particles around Bennu. The goal is to understand the stability, evolution, and final outcome of the simulated particles around the asteroid.…

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…

Neptune's ring arcs confined by coorbital satellites: dust orbital evolution through solar radiation

Silvia Maria Giuliatti Winter, Gustavo Madeira, Rafael Sfair

Voyager 2 images confirmed the presence of ring arcs around Neptune. These structures need a confinement mechanism to constrain their spreading due to collisions, dissipative force…

Asteroid triple system 2001 SN263 : surfaces characteristics and dynamical environment

O. C. Winter, G. Valvano, T. S. Moura +3

The (153591) 2001 SN263 asteroid system, target of the first Brazilian interplanetary space mission, is one of the known three triple systems within the population of NEAs. One of…
