The four main stars that form the asterism are Alpha, Beta, Gamma, and Delta Crucis.

The southern celestial pole lies at the intersection of ( a ) the line along the long axis of crux ( i. e. through Alpha Crucis and Gamma Crucis ) and ( b ) a line perpendicularly bisecting the line joining the " Pointers " ( Alpha Centauri and Beta Centauri ).

Beta Crucis, also known as Mimosa or Becrux, is the second brightest star in the constellation Crux ( after Alpha Crucis or Acrux ) and is the 19th brightest star in the night sky.

Although Beta Crucis, " Becrux ", is at roughly − 60 ° declination, and therefore not visible north of 30 °, in the time of the ancient Greeks and Romans it was visible north of 40 ° due to the precession of equinoxes, and these civilizations regarded it as part of the constellation Centaurus.

Beta Crucis is believed to be the hottest first-magnitude star, with an apparent visual magnitude of 1. 25.

The primary, Beta Crucis A, is a massive star with about 16 times the Sun's mass.

Beta Crucis A is a known Beta Cephei variable, although with an effective temperature of about 27, 000 K it is at the high end of the instability strip where such stars are found.

The Beta Crucis system may be a member of the Lower Centaurus-Crux sub-group of the Scorpius-Centaurus Association.

Thus Beta Crucis appears to the right of the constellation and Delta Crucis to the left, in mirror image of the way they actually appear in the sky ( and, coincidentally, the way they appear on the Brazilian coat of arms ).

The cluster looks like a star to the unaided eye and appears close to the easternmost star of the Southern Cross, ( Beta Crucis ), so is only visible from southern latitudes.

The Jewel Box cluster can be easily located using the star Beta Crucis as a guide, and appears as a fourth magnitude object.

Delta Crucis is a strong candidate Beta Cephei variable and changes its brightness subtly with a period of 1. 3 hours.

The roots of the Vorkosigan Saga lie in an early short story by Bujold, " Dreamweaver's Dilemma ", which features a planet called Beta Colony and a character with the last name of Naismith.

Beta Cephei ( β Cep ) variables, or Beta Canis Majoris variables, as these stars are sometimes called, especially in Europe ) undergo short period pulsations in the order of 0. 1 – 0. 6 days with an amplitude of 0. 01 – 0. 3 magnitudes ( 1 % to 30 % change in luminosity ).

Tigrinya (, tigriñā ), also spelled Tigrigna, Tigrnia, Tigrina, Tigriña, less commonly Tigrinian, Tigrinyan, is a Semitic language spoken in the Tigray Region of Ethiopia ( its speakers there are called " Tigrawot, Tegaru ") by the Tigrinya people, where it has official status, and in central Eritrea, where it is one of the two main languages of Eritrea, and among groups of emigrants from these regions, including some of the Beta Israel now living in Israel.

Beta blockers that target the beta-1 receptor are called cardio selective because beta-1 is responsible for increasing heart rate ; hence a beta blocker will slow the heart rate.

Arthur dies in the fifth installment of the book series, Mostly Harmless, in a club called Beta ( owned by Stavro Mueller ) when the Earth and all its duplicates are simultaneously destroyed by the Grebulons.

Betamax ( also called Beta, and referred to as such in the logo ) is a consumer-level analog videocassette magnetic tape recording format developed by Sony, released in Japan on May 10, 1975.

However, when he realises that Arthur has yet to cause his death at a place called Stavromula Beta, Agrajag discovered he took Arthur out of his relative timeline too soon, and that killing him now would cause a paradox but attempts to kill Arthur anyway.

The Beta Israel use a small gong called a qachel as liturgical accompaniment, though qachel may also refer to a small bell.

Microsoft's implementation of ECMAScript 5th Edition in Windows 8 Consumer Preview is called JavaScript and the corresponding Visual Studio 11 Express Beta includes a “ completely new ”, full-featured JavaScript editor with IntelliSense enhancements for HTML5 and ECMAScript 5 syntax, “ VSDOC ” annotations for multiple overloads, simplified DOM configuration, brace matching, collapsible outlining and “ go to definition ”.

Beta Cephei, traditionally called " Alfirk ", is a double star with a blue-hued giant primary of magnitude 3. 2 and a secondary of magnitude 7. 9.

Mangelwurzel or mangold wurzel ( from German Mangel / Mangold, " chard ", and Wurzel, " root "), also called mangold, mangel beet, field beet and fodder beet, is a cultivated root vegetable derived from Beta vulgaris.

68 Herculis, also called u Herculis, is a Beta Lyrae-type eclipsing binary star.

An extension of the Pi Beta Phi Settlement School called the Craft Work Shop was begun in 1945 in cooperation with the University of Tennessee.

In 2005, Pi Beta Phi began a partnership with a reading awareness program called Read Across America.

The claustrum in those with Parkinson's disease and dementia with Lewy bodies is often affected with Alpha-synuclein neuron inclusions called Lewy bodies and Lewy neurites and Beta amyloid.

In the 1951 film version of the book, also called When Worlds Collide, Bronson Alpha was reimagined as a dwarf star and renamed " Bellus ", while Bronson Beta was designated " Zyra.

Both reciprocating engine and turboprop aircraft can have reverse thrust, and almost all propeller aircraft with reverse thrust have the ability to set the propeller angle to flat pitch ( called Beta range ), which generates no forward or reverse thrust but provides large amounts of drag.

* In astronomy, one of two pairs of stars popularly called " The Pointers ": Alpha Centauri and Beta Centauri, which point to the Southern Cross ; or Alpha Ursae Majoris ( Dubhe ) and Beta Ursae Majoris ( Merak ), which point to Polaris
