This can be done by comparing the apparent magnitudes of the stars …
WebSuch a plot is frequently called the Hertzsprung–Russell diagram, abbreviated H–R diagram. It is one of the most important and widely used diagrams in astronomy, with applications that extend far beyond the purposes for which it was originally developed more than a … Webin the H-R diagram, what are the two most important types of data plotted? spectral classes and absolute magnitudes on the h-r diagram, the bright blue stars that dominate the naked-eye sky lie at the top left On the H-R diagram, the Sun lies about the middle of the main sequence On the H-R diagram, white dwarfs lie Sirius B and Procyon B lie
WebThere are two main processes by which hydrogen fusion takes place in main sequence stars - the proton-proton chain and the CNO (for carbon, nitrogen, oxygen) cycle. Proton-Proton (pp) Chain The main process responsible for the energy produced in most main sequence stars is the proton-proton (pp) chain.
WebThe figure shows a standard Hertzsprung-Russell (H-R) diagram. Label the horizontal and vertical axes using the two blanks nearest the center of each axis, and label the extremes on the two axes using the blanks on the ends of the axes.
