Classifying Stars - The Hertzsprung -Russell Diagram Classifying Stars - the Hertzsprung-Russell Diagram. There are a few hundred billion stars in our galaxy, the Milky Way and billions of galaxies in the Universe. One important technique in science is to try and sort or classify things into groups and seek out trends or patterns. Why is the mass of a star dictates where it lies on the HR Diagram? The Hertzsprung-Russell (HR) Diagram plots a star's color temperature (horizontal scale) against its absolute magnitude or intrinsic brightness (vertical scale) and is Class V dwarfs are the longest lived of all stars and virtually all stars are detectably variable somewhere in the electromagnetic spectrum. Measuring the Age of a Star Cluster | Astronomy 801: Planets, Stars... Star clusters provide us with a lot of information that is relevant to the study of stars in general. The main reason is that we assume that all stars in a Instead of plotting the individual points, they plot a line that goes through the points of all of the stars in the HR diagram. Since this line indicates the... Circumstellar habitable zone - Wikipedia In astronomy and astrobiology, the circumstellar habitable zone (CHZ), or simply the habitable zone, is the range of orbits around a star within which a planetary surface can support liquid water given sufficient atmospheric pressure. The bounds of the CHZ are based on Earth's position in the Solar System and the amount of radiant energy it receives from the Sun.
