Rings of Chariklo

183:, which were observed seven seconds before the beginning of the occultation and seven seconds after the end of the occultation. These secondary occultations indicated that something was partially blocking the light of the background star. The symmetry of the secondary occultations and multiple observations of the event in various locations helped reconstruct not only the shape and size of the object, but also the thickness, orientation, and location of the ring planes. The relatively consistent ring properties inferred from several secondary occultation observations discredit alternative explanations for these features, such as cometary-like outgassing. 3712: 1450: 20: 1444: 1438: 1402: 1902: 2063: 254:
decreased. Also consistent with this edge-on orientation is that since 2008, the Chariklo system has increased in brightness by a factor of 1.5 again, and the infrared water-ice spectral features have reappeared. This suggests that the rings are composed at least partially of water ice. An icy ring composition is also consistent with the expected density of a disrupted body within Chariklo's

Negative detections were recorded by El Catalejo Observatory (Santa Rosa, La Pampa, Argentina), the 20-inch Planewave telescope (part of the Searchlight Observatory Network) at San Pedro de Atacama, Chile and the OALM instrument at Los Molinos Astronomical Observatory in Uruguay. Some of the other participating instruments were those at the National Observatory in Rio de Janeiro, the 447: 3688: 3700: 2052: 131: 253:
The orientation of the rings is consistent with an edge-on view from Earth in 2008, explaining the observed dimming of Chariklo between 1997 and 2008 by a factor of 1.75, as well as the gradual disappearance of water ice and other materials from its spectrum as the observed surface area of the rings

The first conclusion coming from the simulations is that the density of Chariklo has to be bigger than that of the ring matter, just in order to maintain them in orbit. Secondarily, for all tested ring particle radii and ring spatial densities, the rings did cluster in relatively short time scales.

The equivalent depth (a parameter related to the total amount of material contained in the ring based on the viewing geometry) of C1R was observed to vary by 21% over the course of the observation. Similar asymmetries have been observed during occultation observations of Uranus's narrow rings, and

During this event, the observed brightness was predicted to dip from magnitude 14.7 (star + Chariklo) to 18.5 (Chariklo alone) for at most 19.2 seconds. This increase of 3.8 magnitudes is equivalent to a decrease in brightness by a factor 32.5. The primary occultation event was accompanied by four

C2R is half the width of the brighter ring, and resides just outside it, at 404.8 kilometres (251.5 mi). With an optical depth of about 0.06, it is markedly more diffuse than its companion. Altogether, it has approximately a twelfth of the mass of C1R.
