Physical properties of Centaur (60558) 174P/Echeclus from stellar occultations
C. L. Pereira, F. Braga-Ribas, B. Sicardy +42
The Centaur (60558) Echeclus was discovered on March 03, 2000, orbiting between the orbits of Jupiter and Uranus. After exhibiting frequent outbursts, it also received a comet desi…
A large topographic feature on the surface of the trans-Neptunian object (307261) 2002 MS measured from stellar occultations
F. L. Rommel, F. Braga-Ribas, J. L. Ortiz +201
This work aims at constraining the size, shape, and geometric albedo of the dwarf planet candidate 2002 MS4 through the analysis of nine stellar occultation events. Using multichor…
Constraints on (2060) Chiron's size, shape, and surrounding material from the November 2018 and September 2019 stellar occultations
Felipe Braga-Ribas, C. L. Pereira, B. Sicardy +24
After the discovery of rings around the largest known Centaur object, (10199) Chariklo, we carried out observation campaigns of stellar occultations produced by the second-largest…
The changing material around (2060) Chiron from an occultation on 2022 December 15
J. L. Ortiz, C. L. Pereira, B. Sicardy +30
We could accurately predict the shadow path and successfully observe an occultation of a bright star by Chiron on 2022 December 15. The Kottamia Astronomical Observatory in Egypt d…
Enabling discovery of solar system objects in large alert data streams
R. Le Montagner, J. Peloton, B. Carry +5
With the advent of large-scale astronomical surveys such as the Zwicky Transient Facility (ZTF), the number of alerts generated by transient, variable and moving astronomical objec…
The two rings of (50000) Quaoar
C. L. Pereira, B. Sicardy, B. E. Morgado +66
Quaoar is a classical Trans-Neptunian Object (TNO) with an area equivalent diameter of 1,100 km and an orbital semi-major axis of 43.3 astronomical units. Based on stellar occultat…
