Question
The diagram below shows the orbit of a star with an exoplanet and the corresponding radial
velocity curve for the star. Four locations in the planet's orbit are shown. Questions 5-8 refer to
this diagram.
5. For each of the four locations of the planet, mark and label on the star's orbit where the star
would be at that time.
6. For each of the four positions of the star, draw arrow to indicate which way the star is moving
at that time.
7. For each of the four positions of the star, indicate whether the star's light is redshifted,
blueshifted, or not shifted.
8. Mark and label the positions on the radial velocity curve that correspond to the four letters.
Remember that positive radial velocities correspond to the star moving away from the Earth!!
