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.

- Use this interactive simulation of stellar parallax. Change the distance to the star to values given in column 2. Write down the parallax angle in arcsec for each distance. Convert the parallax angle to radians. Calculate the distance. If your calculation is correct, your number in the last column should be similar to the number in column 2 (NOT THE SAME!). 1 AU is 4.85 x 10-6 pc (Don't write units with your answer!) Measured (true) Parallax angle n (in radians) (use 2 significant D (round your answer to 2 figures) Calculated distance Object Parallax angle (in arcsec) Distance from Position "Sun" in pc decimal places) Nearest 0.5 Intermediate 1 Farthest 1.5arrow_forwardUse a diagram to explain what is meant by the parallax angle, p, for a star observed twice from Earth, with a 6-month interval between each observation. Hence define the parsec, and calculate its value in astronomical units and metres. The star Betelgeuse is observed to have a parallax angle p = 4.5 × 10−3 arcseconds.
