Stars come in a wide range of temperatures sizes masses and colors The constellation of Orion is a good example of the variety of stars How can we learn about stars Suppose you are an alien with three days to learn everything you can about the human species. Richard B. . Larson. Yale University. Conclusions. Compact objects such as stars and black holes generally form in larger systems such as binaries, multiple systems, star clusters, or galaxies.. Gravitational interactions in these larger systems play a major role in the formation of compact objects by transporting angular momentum.. By Laura Lush. . . By Sephy Vandekamp. Stars.
