(kərē`nə) [Lat.,=the keel], southern constellationconstellation,
in common usage, group of stars that appear to form a configuration in the sky; properly speaking, a constellation is a definite region of the sky in which the configuration of stars is contained.

in astronomy, 2d brightest star in the sky, located in the constellation Carina, which is part of the ancient constellation Argo Navis; Bayer designation α Carinae; 1992 position R.A. 6h23.8m, Dec. −52°41'.

In the 1840s a nova associated with η Carinae, a binary star consisting of a massive star with at least 90 times the mass of the sun (and perhaps more than 120 times the mass) and a companion with about 30 times the sun's mass, was observed in Carina. The nova made η Carinae the second brightest star in the sky for a time, and produced the Homunculus Nebula. The star also lies within the much larger Eta Carinae Nebula, one of the largest diffuse nebulae. Carina reaches its highest point in the evening sky in March.

Carina

(kă-ree -nă, -rÿ ) (Keel) A constellation in the southern hemisphere near Crux. It was once part of the constellation Argo. The brightest stars are the bright white giant Canopus (α) and some 1st-and 2nd-magnitude stars. The irregular variable star Eta (η) Carinae is associated with extensive nebulosity (see Eta Carinae; Eta Carinae Nebula). The area also contains two open clusters: the 2nd-magnitude IC 2602, centered on Theta (θ) Carinae, and the brilliant NGC 3532, located just west of Eta Carinae; and the large globular cluster NGC 2808. Abbrev.: Car; genitive form: Carinae; approx. position: RA 9h, dec –60°; area: 494 sq deg.

Carina

 

(in birds, keel), a longitudinal process of the sternum that serves for attachment of the well-developed pectoral muscles in a number of vertebrates.

The presence of the carina is connected with the character of movement of the anterior extremities: a carina is present in some rooting animals (moles) and is especially well developed in flying animals (the extinct flying lizards, or pterosaurs; birds; bats). In birds, the degree of development and particular features of the shape of the keel are associated with the type of flight. Carinatae, which fly well (for example, hummingbirds and martlets), have an especially large keel. A keel is also present in birds that are incapable of flight but swim by means of their wings (for example, penguins). In flightless birds (ostriches, certain water rails, and parrots), the keel is absent or very poorly developed. In some swans and cranes the keel is hollow and encloses part of the convoluted trachea, which acts as a resonator.

[kə′rī·nə] (astronomy) A constellation, right ascension 9 hours, declination 60°S. Abbreviated Car. Also known as Keel.
