    Have a question which I have no idea how to answer, which I think is supposed to be fairly basic.

    Q) The maximum observed seperation between two stars is 3.7 arcseconds. Assuming orbits are circular, calculate the radii of the orbits in AU.

    There was a question previous to this so I am not sure if you need to use the information in that question to work this out but I am completely stumped.

    Any help appreciated. Thanks.
