WebLearning the processes that form binary star systems. Many mature stars are in binary or multiple systems. Astronomers think most stars probably formed as pairs, which sometimes are broken up by encounters with other stars. ... Depending on its size, a star-forming … WebOnly the gradual depletion of hydrogen as it is transformed into helium in the core slowly changes the star’s properties. The mass of a star determines exactly where it falls on the main sequence. As Figure 21.12 shows, massive stars on the main sequence have high temperatures and high luminosities. Low-mass stars have low temperatures and ...
