Web2 de mar. de 2024 · Hertzsprung Russell Diagram. The HR diagram is the "Rosetta Stone" of stellar astronomy. It was created in 1910 by Ejnar Hertzsprung and Henry Norris Russell. It plots a star's luminosity against its surface temperature. As simple as that sounds, it is the key to understanding stellar evolution. Web7 de out. de 2024 · You can use an HR diagram along with calibrated evolutionary models to find the distance (and in some cases, mass and age) of individual stars. The method is known as spectroscopic parallax.This is a confusing name because it is not a parallax measurement at all. The technique is to use spectroscopy, or less precisely the colours, …
