The Hertzsprung–Russell diagram (abbreviated as H–R diagram, HR diagram or HRD) is a scatter plot of stars showing the relationship between the stars' absolute magnitudes or luminosities and their stellar classifications or effective temperatures.
El diagrama de Hertzsprung-Russell (comúnmente abreviado como diagrama H-R) es un gráfico de dispersión de estrellas que indica la relación entre las magnitudes absolutas o luminosidades de las estrellas en comparación con sus clasificaciones espectrales o las temperaturas efectivas.
Hertzsprung-Russell diagram, in astronomy, graph in which the absolute magnitudes (intrinsic brightness) of stars are plotted against their spectral types (temperatures). The Sun lies near the middle of the main sequence on the diagram.
Learn how to use the H-R diagram to plot and interpret the temperature and luminosity of stars. Find out the different groups of stars and how to infer their properties from their positions on the diagram.
Learn how astronomers use the Hertzsprung-Russell diagram to trace the evolutionary stage of a star. Explore the different phases of star formation, life and death with videos and scientific case.
El diagrama Hertzsprung—Russell, o diagrama H—R, es una gráfica de luminosidad estelar frente a la temperatura superficial. La mayoría de las estrellas se encuentran en la secuencia principal, que se extiende diagonalmente a través del diagrama H-R desde alta temperatura y alta luminosidad hasta baja temperatura y baja luminosidad.
The Hertzsprung–Russell diagram, or H–R diagram, is a plot of stellar luminosity against surface temperature. Most stars lie on the main sequence, which extends diagonally across the H–R diagram from high temperature and high luminosity to low temperature and low luminosity.
