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…

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…

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…

A high geometric albedo and small size of the Haumea cluster member (24835) 1995 SM55 from a stellar occultation and photometric observations

J. L. Ortiz, N. Morales, B. Sicardy +98

Trans-Neptunian objects (TNOs) are among the most ancient bodies of the solar system. Understanding their physical properties is key to constraining their origin and the evolution…

Size and Shape of Jupiter Trojan (2207) Antenor from Stellar Occultations

Feliphe S. Ferreira, Julio I. B. Camargo, Bruno E. Morgado +34

Librating around the Lagrange L5, the Jupiter's Trojan (2207) Antenor has been observed in recent years and its rotational light curve suggests it to be a very likely binary astero…

Size and shape of the trans-Neptunian object (470316) 2007 OC10: Comparison with thermal data

J. M. Gómez-Limón, R. Leiva, J. L. Ortiz +40

The shapes of only 12 trans-Neptunian objects have been directly measured, offering crucial insights into their internal structure. These properties are strongly connected to the p…

Investigating the formation of small Solar System objects using stellar occultations by satellites: present, future and its use to update satellite orbits

Felipe Braga-Ribas, Frederic Vachier, Josselin Desmars +2

The history of the outer solar system is intrinsically related to the Giant Planets migration. A massive disk of material within a radius of 30~au was scattered during the planetar…

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…

Orbit determination of Transneptunian objects and Centaurs for the prediction of stellar occultations

J. Desmars, J. I. B. Camargo, F. Braga-Ribas +10

The prediction of stellar occultations by Transneptunian objects and Centaurs is a difficult challenge that requires accuracy both in the occulted star position as for the object e…
