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…
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…
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…
Stellar occultation observations of (38628) Huya and its satellite: a detailed look into the system
F. L. Rommel, E. Fernández-Valenzuela, B. C. N. Proudfoot +78
The physical and orbital parameters of Trans-Neptunian Objects (TNOs) provide valuable information about the Solar System's formation and evolution. In particular, the characteriza…
Physical properties of trans-Neptunian object (143707) 2003 UY117 derived from stellar occultation and photometric observations
M. Kretlow, J. L. Ortiz, J. Desmars +49
Trans-Neptunian objects (TNOs) are considered to be among the most primitive objects in our Solar System. Knowledge of their primary physical properties is essential for understand…
A study of centaur (54598) Bienor from multiple stellar occultations and rotational light curves
J. L. Rizos, E. Fernández-Valenzuela, J. L. Ortiz +40
Centaurs, distinguished by their volatile-rich compositions, play a pivotal role in understanding the formation and evolution of the early solar system, as they represent remnants…
The stellar occultation by (319) Leona on 13 September 2023 in preparation for the occultation of Betelgeuse
J. L. Ortiz, M. Kretlow, C. Schnabel +36
On 12 December 2023, the star Orionis (Betelgeuse) will be occulted by the asteroid (319) Leona. This represents an extraordinary and unique opportunity to analyze the diameter…
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…
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…
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…
The multichord stellar occultation by the centaur Bienor on January 11, 2019
E. Fernández-Valenzuela, N. Morales, M. Vara-Lubiano +42
Within our program of physical characterization of trans-Neptunian objects and centaurs, we predicted a stellar occultation by the centaur (54598) Bienor to occur on January 11, 20…
Physical properties of the trans-Neptunian object (38628) Huya from a multi-chord stellar occultation
P. Santos-Sanz, J. L. Ortiz, B. Sicardy +85
Within our international program to obtain accurate physical properties of trans-Neptunian objects (TNOs) we predicted a stellar occultation by the TNO (38628) Huya of the star Gai…
The multichord stellar occultation on 2019 October 22 by the trans-Neptunian object (84922) 2003 VS
M. Vara-Lubiano, G. Benedetti-Rossi, P. Santos-Sanz +60
We predicted, observed, and analyzed the multichord stellar occultation of the Second Gaia Data Release (Gaia DR2) source 3449076721168026624 (m = 14.1 mag) by the plutino obje…
The 2017 May 20 stellar occultation by the elongated centaur (95626) 2002 GZ
P. Santos-Sanz, J. L. Ortiz, B. Sicardy +56
We predicted a stellar occultation of the bright star Gaia DR1 4332852996360346368 (UCAC4 385-75921) (m= 14.0 mag) by the centaur 2002 GZ for 2017 May 20$^{\rm th}…
