- Calculate the mass of a star having a diameter of 6E5 km and an average density of 1.1 g/cm3Indicate whether the following are properties of Type Ia or Type II supernovae. (Select 1-Type Ia, 2-Type II. If the first is 1 and the rest 2, enter 12222222). A) Can occur in a very old star cluster. B) Can only occur in a binary system. C) The spectrum shows strong Hydrogen lines D) Produces very heavy elements like Uranium during the explosion. F) Could completely explode and leave no remnant behind. Supernovae of this type have the same peak luminosity.using the center-of-mass equations or the Carter of Mass Calculator (under Binary-Star Basics, abova), you will investigate a specific binary star system. Assume that Star 1 has m, 3.2 solar masses, Star 2 has m,-0.9 solar masses, and the total separation of the two (R) is 34 All (One AU is Earth's average distance from the Sun) (2) What is the distance, d. (In Au) from Star 1 to the center of mass? AU (b) What is the distance, dy On Au) from Star 2 to the center of mass AU ( what is the ratio of d, tod?

What is its absolute magnitude? Round your answer to two significant figures.If an X-ray binary consists of a 16 solar mass star and a neutron Star orbiting each other every 15.4 days, what is their average separation? (Hint: Use the version of Keller's third law for binary stars, Ma + Mb = a^3 /p^2 ; make sure you express quantities in unites of AU, solar masses, and years. Assume the mass of a neutron Star is 1.6 solar masses.) ___________ AU
