The subtle beauty of the Hertzsprung-Russel diagram

<p>As a stellar astrophysicist myself, I can&rsquo;t help but falling in love with this diagram, which is the key in the understanding of stellar evolution and stellar population analysis.</p> <p>This tool was developed independently by Ejnar Hertzsprung and Henry Norris Russell in the early 1900s. What it does is pretty cool &mdash; it plots stars&rsquo; temperature against their luminosity, in order to show how star color (spectral type) relates to their absolute brightness, which we call a Color-Magnitude Diagram (CMD).</p> <p><a href="https://medium.com/@arthurmaga/the-subtle-beauty-of-the-hertzsprung-russel-diagram-812397f711fc"><strong>Click Here</strong></a></p>
