Size, shape, density, and atmospheric limit of (50000) Quaoar revealed from 14 years of stellar occultation
Giuliano Margoti, Felipe Braga-Ribas, José Luis Ortiz +173
We present results from 28 stellar occultations by the large Trans-Neptunian Object (50000) Quaoar registered between 2018 and 2025. By performing a joint analysis of this occultat…
StreakMind: AI detection and analysis of satellite streaks in astronomical images with automated database integration
Rafael Carrillo Navarro, René Duffard, Pablo GarcÃa-MartÃn +3
Artificial satellites and space debris increasingly contaminate astronomical images, affecting scientific surveys and producing large volumes of streaked exposures. Manual inspecti…
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…
A catalog of near-IR absolute magnitudes of Solar System small bodies
Alvaro Alvarez-Candal, Juan Luis Rizos, Milagros Colazo +5
Context. Phase curves of small bodies are useful tools to obtain their absolute magnitudes and phase coefficients. The former relates to the object's apparent brightness, while the…
