The Centaur object 2060 Chiron, located between Saturn and Uranus, has been found to have a transforming disk of dust around it that changes shape and can mimic rings. Observations during stellar occultations in 2011 and 2018 revealed the presence of dusty material at different distances from Chiron's center, suggesting an evolving system rather than stable rings. Another occultation in 2022 detected three symmetrical structures forming a wide disk around Chiron. The origin and composition of this material remain unknown, but it is likely to come from Chiron itself. These findings also raise questions about the nature of the structures around another Centaur, Chariklo.
The Centaur object 2060 Chiron, a captured cometary object that orbits between Jupiter and Neptune, has been found to have a transforming disk of dust around it that changes shape and can mimic rings. Observations during stellar occultations in 2011 and 2018 revealed the presence of dusty material at different distances from Chiron's center, suggesting an evolving system rather than stable rings. Another Centaur, 10199 Chariklo, was previously shown to have rings, but the findings at Chiron raise questions about the nature of the structures around Chariklo as well. The origin and composition of the material around Chiron remain unknown.
Observations during a stellar occultation of Centaur Chiron have revealed the presence of evolving material orbiting the object, rather than a stable ring system. The data collected suggests that the material surrounding Chiron is currently changing and evolving, ruling out the possibility of a two-ring system. This finding provides valuable insights into the formation and dynamics of rings around small celestial bodies.
