Ast 3018 Homework #4 - Due Thursday November 5, 2009 Chapter 5 Problems 5.3 5.16 5.19 5.20 (Problem 7.6 from the book Modern Astrophysics by Carroll & Ostlie) From the light and velocity curves of an eclipsing spectroscopic binary star system, it is determined that the orbital period is 6.31 years and the maximum radial velocities of stars A and B are 5.4 km/sec and 22.4 km/sec respectively. Furthermore, the time period between first contact and minimum light (t b

Unformatted text preview: -t a ) is 0.58 days, the length of the primary minimum (t c-t b ) is 0.64 days and the apparent bolometric magnitudes of maximum, primary minimum and secondary minimum are 5.4, 9.20 and 5.44 magnitudes respectively. From this information, and assuming circular orbits, find the a. ratio of stellar masses b. sum of the masses (assume i=90) c. individual masses d. individual radii e. ratio of the effective temperatures of the two stars.
