The 23 pages that link to Stellar luminosity, each with the reason it gives.

• Stellar classificationRelated: Luminosity classes distinguish stars that share a spectral type but differ in intrinsic brightness.

• Main sequenceRelated: Luminosity is the vertical quantity used to locate stars on the Hertzsprung–Russell diagram.

• Hertzsprung–Russell diagramRelated: It supplies the brightness coordinate, often expressed relative to the Sun.

• Stellar parallaxRelated: A parallax distance converts observed brightness into intrinsic luminosity.

• Red giantRelated: Red giants radiate strongly despite having relatively cool surfaces, because their radiating areas are enormous.

• Habitable zoneRelated: A star’s energy output largely determines how far its habitable zone extends.

• Stellar structureRelated: Luminosity is the outward energy flow that interior transport must carry.

• Stellar massCompared with: Luminosity correlates with mass but is not itself a measure of matter.

• Stellar radiusRelated: Its value, paired with effective temperature, constrains the star’s size.

• Red dwarfRelated: Red dwarfs emit little energy compared with more massive stars.

• Red supergiantRelated: A vast emitting surface makes a cool red supergiant highly luminous.

• Antonia MauryRelated: Maury used differences in spectral-line appearance to distinguish stars with different intrinsic luminosities.

• StarRelated: Luminosity measures a star’s intrinsic energy output, unlike its apparent brightness from Earth.

• Henry Norris RussellRelated: Luminosity became one axis of the diagram Russell used to compare stars.

• Instability stripRelated: Luminosity supplies one coordinate used to locate the strip and its stars.

• Red-giant branchRelated: Shell fusion raises luminosity as stars ascend the branch.

• SubgiantRelated: A subgiant is more luminous than a main-sequence star of similar temperature.

• Hayashi trackRelated: A contracting star’s luminosity generally declines as it moves down the track.

• Giant starRelated: High luminosity, rather than size alone, is central to the giant classification.

• SupergiantRelated: Exceptional intrinsic luminosity is the defining trait behind the supergiant classification.

• HypergiantNarrower topic: Hypergiants are defined by extraordinary luminosity, not merely by apparent brightness.

• UY ScutiRelated: Its luminosity helps astronomers infer UY Scuti’s radius and distance.

• LBV 1806−20Related: Uncertainty in LBV 1806−20’s distance changes its inferred intrinsic luminosity.
