WebThe above HR diagram shows the evolutionary path of a sunlike star after it leaves the main sequence. From stage 7 (main sequence star) to stage 8 (subgiant), the surface temperature of the star declines as the core fills and hydrogen fusion begins to take place in a shell around the core. The luminosity increases as the star expands into a ... WebFigure 21.12 Evolutionary Tracks for Contracting Protostars. Tracks are plotted on the H–R diagram to show how stars of different masses change during the early parts of their lives.

WebThe Hertzpsrung-Russell (H-R) diagram is a way of categorizing properties of all stars in the sky, including the Sun. The surface temperature, color, luminosity, and radius of stars can all be deduced from their location on the H-R diagram. When a star begins to condense from an interstellar dust cloud, it enters the HR diagram in the middle right. WebThe HR diagram can be seen as both a snapshot of the state of a large collection of stars, or a generalization of the evolutionary pathways of individual stars.
