Mizar and Alcor

Mizar and Alcor form a naked eye double star in the handle of the Big Dipper asterism in the constellation Ursa Major. Mizar is itself a quadruple system and Alcor is a binary, the pair together forming a sextuple system.

Description

Mizar (Zeta Ursae Majoris, Zeta UMa, ζ Ursae Majoris, ζ UMa, known as Arundhati-Vasishtha in Sanskrit (अरुन्धती-वशिष्ठ) and in Arabic as "المئزر" (mīzar, meaning a waistband or girdle) is a quadruple system, a visual double with a separation of 14.4 arcseconds, each of which is a spectroscopic binary, in the constellation Ursa Major and is the second star from the end of the Big Dipper's handle. Its apparent magnitude is 2.23 and its spectral class is A2V.

With normal eyesight one can make out a faint companion about 12 minutes of arc from Mizar, named Alcor or 80 Ursae Majoris. Alcor is of magnitude 3.99 and spectral class A5V. It has a faint red dwarf companion separated by 1".

Mizar and Alcor's proper motions show they move together (they are both members of the Ursa Major Moving Group), but it has yet to be demonstrated conclusively that they are gravitationally bound. Recent studies indicate that the Alcor binary and Mizar quadruple are somewhat closer together than previously thought: approximately 74,000 ± 39,000 astronomical units or 0.5–1.5 light years.

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.
