Canopus

Canopus (/kəˈnpəs/; α Car, α Carinae, Alpha Carinae) is the brightest star in the southern constellation of Carina, and the second brightest star in the night-time sky, after Sirius. Canopus's visual magnitude is 0.72, and it has an absolute magnitude of 5.65.

Canopus is a supergiant of spectral type F. Canopus is essentially white when seen with the naked eye (although F-type stars are sometimes listed as "yellowish-white"). It is located in the far southern sky, at a declination of 52° 42' (2000) and a right ascension of 06h24.0m.

Its name comes from the mythological Canopus, who was a navigator for Menelaus, king of Sparta.

Observational history

In Indian Vedic literature, the star Canopus is associated with the sage Agastya, one of the ancient rishis (the others are associated with the stars of the Big Dipper). Agastya, the star, is said to be the 'cleanser of waters' and its rising coincides with the calming of the waters of the Indian Ocean. It is considered the son of Pulasthya, son of Brahma.

Growth–share matrix

The growth–share matrix (aka the product portfolio, BCG-matrix, Boston matrix, Boston Consulting Group analysis, portfolio diagram) is a chart that was created by Bruce D. Henderson for the Boston Consulting Group in 1970 to help corporations to analyze their business units, that is, their product lines. This helps the company allocate resources and is used as an analytical tool in brand marketing, product management, strategic management, and portfolio analysis. Analysis of market performance by firms using its principles has recently called its usefulness into question.

Overview

To use the chart, analysts plot a scatter graph to rank the business units (or products) on the basis of their relative market shares and growth rates.

  • Cash cows is where a company has high market share in a slow-growing industry. These units typically generate cash in excess of the amount of cash needed to maintain the business. They are regarded as staid and boring, in a "mature" market, yet corporations value owning them due to their cash generating qualities. They are to be "milked" continuously with as little investment as possible, since such investment would be wasted in an industry with low growth.
  • Star (Erasure song)

    "Star" is a song by Erasure, released in 1990 as the fourth European (and third American) single from the group's fourth studio album Wild!.

    A straightforward dance music track with disco elements, "Star" was written by Erasure members Vince Clarke and Andy Bell, its lyrical content clearly referencing nuclear war; Erasure's own form of protest song. When released as a single, the track was remixed slightly for radio, bringing acoustic guitar elements and various background vocal parts forward in the mix.

    The last single released from Wild!, "Star" became Erasure's twelfth consecutive Top 20 hit on the UK singles chart, peaking at number eleven, and in Germany it peaked at number twenty-three. In the United States, "Star" did not enter the Billboard Hot 100, although it became a popular club hit, climbing to number four on the U.S. Hot Dance Music/Club Play chart.
