Let us imagine that the spectrum of a star is collected and we find the absorption line of Hydrogen-Alpha (the deepest absorption line of hydrogen in the visible part of the electromagnetic spectrum) to be observed at 656.5 nm instead of 656.3 nm as measured in a lab here on Earth. What is the velocity of this star in m/s? (Hint: speed of light is 3*10^8 m/s; leave the units off of your answer)

Using the center-of-mass equations or the Center of Mass Calculator (under Binary-Star Basics, above), you will investigate a specific binary-star system. Assume that Star 1 has  m1 = 3.2  solar masses, Star 2 has  m2 = 1.6  solar masses, and the total separation of the two (R) is 80 AU. (One AU is Earth's average distance from the Sun.) (a) What is the distance,  d1,  (in AU) from Star 1 to the center of mass?
