Problem 5. Imagine that you observe a star field twice, with a six-month gap between
your observations, and that you see the two sets of stars shown below. Which do you think
is closest to the observer?
Figure 1: Schematic of image of stars A,B, and P taken six months apart.
Problem 6. Suppose the angular separation between stars A and B is 0.5 arcseconds. How
far would you estimate star P to lie from the observer?
The stars in a CCD image include stars in a cluster and stars in front of the cluster (i.e. starts that don't
belong to it). One group has parallaxes clustered around of 3 milli-seconds of arc (or "3 mas"). The parallaxes of
the other group range from 10 mas to 15 mas. Which group contains the stars in the cluster? Explain your
answer.
