Where does star collide?

A graph in which a single central point is joined by an edge to every other point, and no other edges exist, so the whole structure fans out from one hub: this is the star graph, written K_{1,n} for n outer points. Harary's 1969 Graph Theory gives this as the standard definition, and the same shape names the star topology in which every device connects only to one central node. The referent is an abstract pattern of points and connections, counted by the number of outer points, and it is not a burning sphere in space, a celebrated person, or a quality grade.[1]

Unit

One central point joined to n outer points, with no edges among the outer points

Recovery means

Not applicable

Measured by

Described by its point and edge counts and by structural properties such as its diameter of two and its single hub of degree n

A performer who has become widely famous and whose image is produced, circulated, and marketed as a valuable public figure, together with the industrial star system that manufactures such fame. Dyer's 1979 Stars treated the film star not as a mere individual but as a constructed image carrying social meaning, made through films, publicity, and audience reception. The referent is a person and the apparatus of fame around them, gauged by audience reach and drawing power, and it is a different thing entirely from a fusing sphere of plasma, a hub in a graph, or a mark awarded for quality.[2]

Unit

One publicly celebrated performer and the image marketed around them

Recovery means

Not applicable

Measured by

Traced through box-office draw, media coverage, fan following, and the publicity apparatus of the star system

A unit on an ordinal scale, usually running from one to five, used to grade the quality of something such as a hotel, a film, or a product, so that more stars is taken to mean better. de Langhe, Fernbach, and Lichtenstein's 2016 Navigating by the Stars studied average online star ratings as quality signals and found they often diverge from objective quality even as buyers lean heavily on them. The referent is a mark on a measurement scale, counted in whole or fractional stars, and it is unrelated to a body in space, an abstract graph, or a famous performer, even though a hotel and a movie idol are both loosely called stars.[3]

Unit

One graded mark on an ordinal quality scale, typically one to five stars

Recovery means

Not applicable

Measured by

Recorded as counts or averages of assigned stars, and assessed against objective quality benchmarks and rater agreement
