Epsilon Eridani

Epsilon Eridani (ε Eri, ε Eridani), or Ran, is a star in the southern constellation Eridanus, along a declination 9.46° south of the celestial equator. This allows it to be viewed from most of Earth's surface. At a distance of 10.5 light years (ly), it has an apparent magnitude of 3.73. It is the third closest individual star or star system visible to the unaided eye and was the closest star known to host a planet until the unconfirmed discovery of Alpha Centauri Bb. Its age is estimated at less than a billion years. Because of its youth, Epsilon Eridani has a higher level of magnetic activity than the present-day Sun, with a stellar wind 30 times as strong. Its rotation period is 11.2 days at the equator. Epsilon Eridani is smaller and less massive than the Sun, and has a comparatively lower level of elements heavier than helium. It is a main-sequence star of spectral class K2, which means that energy generated at the core through nuclear fusion of hydrogen is emitted from the surface at a temperature of about 5,000 K, giving it an orange hue.

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.

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.
