<h3>The Hertzsprung–Russell diagram, or H–R diagram, is a plot of stellar luminosity against surface temperature. Most stars lie on the main sequence, which extends diagonally across the H–R diagram from high temperature and high luminosity to low temperature and low luminosity.</h3><h2>____________________(◕ᴗ◕✿)</h2><h2><u>PLEASE</u><u> </u><u>MARK</u><u> ME</u><u> BRAINLIEST</u><u> AND</u><u> FOLLOW</u><u> ME</u><u> LOTS</u><u> OF</u><u> LOVE</u><u> FROM</u><u> MY</u><u> HEART'AND</u><u> SOUL</u><u> DARLING</u><u> TEJASVINI</u><u> SINHA</u><u> HERE</u><u> ❤️</u></h2>
