- Calculate the mass of a star having a diameter of 6E5 km and an average density of 1.1 g/cm3Consider three main sequence stars: Star A is 14,500 K, Star B is 2,900 K, and Star C is 5,500 K. What are the colors of each of these stars?If a star has a parallax of 0.050 arc second, what is its distance in pc?
- List the following 5 terms in order through a stars life cycle (starting with the sun), through the remainder of its lifetime: a. Black dwarf b. Planetary nebula c. Red giant d. Star (Sun) e. White dwarfWhich statement is most logical? a First stars are thought to have been more massive than Sun because the materials used to make clouds were more abundant at the beginning b First stars are thought to have been more massive than Sun because the temperatures of the clouds that made them were higher because they consisted entirely of hydrogen and helium c First stars are thought to have been more massive than Sun because star-forming clouds were much denser early in time d First stars are thought to have been more massive than Sun because the clouds that made them were much more massiveA star with a trigonometric parallax of .02 arcseconds has a distance of O2.0 light years. 50 pc. 4 kpc. 20 pc.
