- 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 massiveQuestion A1 Use a diagram to explain what is meant by the parallax angle, p, for a star observed twice from Earth, with a 6-month interval between each observation. Hence define the parsec, and calculate its value in astronomical units and metres. The star Betelgeuse is observed to have a parallax angle p = 4.5 x 10-³ arcseconds. State the distance of Betelgeuse in units of parsecs and light years.
