952 Caia

952 Caia, provisional designation 1916 Σ6₁, is a large carbonaceous asteroid from the outer region of the asteroid belt, about 82 kilometers in diameter. It was discovered by Soviet–Russian astronomer Grigory Neujmin at the Crimean Simeiz Observatory on 27 October 1916.

The C-type asteroid orbits the Sun at a distance of 2.3–3.7 AU once every 5 years and 2 months (1,887 days). Its orbit shows an eccentricity of 0.25 and an inclination of 10 degrees from the plane of the ecliptic.

Two photoelectric light-curve observations from 1980 rendered a rotation period of 7.50 and 7.51 hours, while a more recent light-curve analysis in 2004 gave a period of 7000379500000000000♠3.795±0.001 hours (or half the previously determined period) with a very low brightness variation of 0.03 in magnitude, which typically indicates a nearly spheroidal shape. According to the surveys carried out by the Infrared Astronomical Satellite, IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, the asteroid has a diameter between 81.6 and 88.8 kilometers and a low albedo in the range of 0.040 and 0.056. The Collaborative Asteroid Lightcurve Link agrees with the spaced-based observations and derives an albedo of 0.051 with a corresponding diameter of 81.5 kilometers.

Caia (river)

The Caia is a river in the Iberian Peninsula, a tributary to the Guadiana. It is one of the main water courses in the Portalegre District, Portugal. Portugal does not recognise the border between the Caia and Ribeira de Cuncos River deltas, since the beginning of the 1801 occupation of Olivenza by Spain. This territory, though under de facto Spanish occupation, remains a de jure part of Portugal, consequently no border is henceforth recognised in this area.

Course

It has its sources in the Serra de São Mamede and for the lower 11 kilometres (7 mi) of its course it forms the international Portugal-Spain border. Finally it joins the Guadiana River southwest of the city of Badajoz.

Caia (music)

Caia /ˈtʃaɪ.ə/, pronounced "ch-AYE-ah", is a collaborative effort of electronica/dance artists Maiku Takahashi and Andy Cato of Groove Armada and The Weekend Players. Their only known album, The Magic Dragon, was released in April 2003, whose sound can be described as ambient, trip-hop, and dance. Produced by Cato and mixed by Takahashi, the effort's only album has light and airy beats that have rich drum beats and beautiful synth strings.

The first track on the album, The Rose Room's drum beat has a bass-rich sound and synth, with ambient voices and a calming sound. Remembrance is a 7-minute long instrumental that has light electric piano sounds and a dreamy synth, with ambient voices calling out from the background. Following that is The Love Room, which has a sound similar to that of The Rose Room with its bass rich drum beat, but has a bit of a darker, minor sound compared to the light, major chords ever-present in The Rose Room and Remembrance. The fourth track, Summer Lightning, is aptly named, for its dreamy bongo-esque drum beat and light dreamy instrumental noise about it. La Telecabine has a light sound that escalates to a pounding drum beat with dreamy instrumentals, and calming down as the song ends and transfers to Mr. Gone. Heavy Weather and Subway Freedom share the same vibe of an African-sounding bongo drum and a light instrumental tone that swiftly transitions to a louder, richer, and bass-enhanced sound, then calms down similar to Remembrance and Summer Lightning. Finally, Afterwards @ The Bar has a very calm, instrumental noise that ends the short-lived group's only album like it's falling into a deep sleep.
