Webthe HR diagram as the path of the star as it moves away from the horizontal branch towards a region of lower temperature and in the case of lower mass stars, higher luminosity. The star is now becoming a red supergiant (Chaisson and McMillan, Hurley et al. 2000). Carbon/Oxygen White Dwarfs - the Fate of Medium Mass Stars WebHertzsprung–Russell diagram for globular cluster M5, with the horizontal branch marked in yellow, RR Lyrae stars in green, and some of the more luminous red-giant branch stars in red The horizontal branch ( HB) is a stage of stellar evolution that immediately follows the red-giant branch in stars whose masses are similar to the Sun 's.
WebThe H-R diagram is a scatter graph of stars – a plot of stellar absolute magnitude or luminosity versus surface temperature or stellar classification. Stages of stellar evolution occupy specific regions on the H-R diagram and exhibit similar properties. ... The HB stars have left the red giant branch and are characterized by helium fusion in ... WebThis produces the “red giant branch” as progressively less massive stars also run out of fuel; the corner or bend where the main sequence leads into the red giant branch is called the “main sequence turn-off,” or sometimes just the turn-off. ... And since an HR diagram plots decreasing temperature on the x-axis, what does that imply ...
http://khadley.com/Courses/Astronomy/ph_206/topics/starEvolution/h-r-diagram.html 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.
