The trans-Neptunian object (119951) 2002 KX14 revealed via multiple stellar occultations
J. L. Rizos, J. L. Ortiz, F. L. Rommel +55
(119951) 2002 KX14 is a large classical TNO with limited previous observations and unresolved questions regarding its physical properties. Five stellar occultations by 2002 KX14 we…
Constraining the size, shape, and albedo of the large Trans-Neptunian Object (28978) Ixion with multi-chord stellar occultations
Y. Kilic, F. Braga-Ribas, C. L. Pereira +81
Trans-Neptunian objects (TNOs) are among the most primitive remnants of the early Solar System, and constraining their sizes, shapes, albedos, and surface properties is essential f…
Rings around irregular bodies. II. Numerical simulations of the 1/3 spin-orbit resonance confinement and applications to Chariklo
Heikki Salo, Bruno Sicardy
Rings have been found around Chariklo, Haumea and Quaoar, three small objects of the Solar System. All these rings are observed near the second-order spin-orbit resonances (SORs) 1…
JWST occultation reveals unforeseen complexity in Chariklo's ring system
Pablo Santos-Sanz, Altair R. Gomes-Júnior, Bruno E. Morgado +25
Ring systems have been discovered around several small bodies in the outer Solar System through stellar occultations. While such measurements provide key information about ring geo…
The rings of (2060) Chiron: Evidence of an evolving system
C. L. Pereira, F. Braga-Ribas, B. Sicardy +54
The centaur (2060) Chiron has long been a candidate for hosting material in orbit, based on occultation and photometric and spectroscopic data. Here, we present a multichord stella…
Rings around irregular bodies I. Structure of the resonance mesh, applications to Chariklo, Haumea and Quaoar
Bruno Sicardy, Heikki Salo, Maryame El Moutamid +2
Three ring systems have been discovered to date around small irregular objects of the solar system (Chariklo, Haumea and Quaoar). For the three bodies, material is observed near th…
