1. Briefly describe the basic chain of events leading to the formation of a star like the Sun.
2. What are the roles of heat, rotation and magnetism in the process of stellar birth?
3. What is an evolutionary track?
CST 1 – 3
1. If a newly forming star has an excess of heat, then it will likely have (a) more gravity; (b) less gravity; (c) a slower contraction rate; (d) a rapid contraction rate.
2. The gravitational contraction of an interstellar cloud is primarily the result of its (a) mass; (b) composition; (c) diameter; (d) pressure.
3. The interstellar cloud from which our Sun formed was (a) slightly larger than the Sun; (b) comparable in size to Saturn's orbit; (c) comparable in mass to the solar system; (d) thousands of times more massive than the Sun.
