Unformatted text preview: Physics 341: Problem Set #10 due November 18 You are encouraged to work in groups on these problems, but each student must write up the solutions individually. You must also list your collaborators on your solutions, and cite any external sources you used (other than the course notes or textbook). I will give partial credit for partial answers, but only if you show your work and explain your reasoning. Be careful with units. 1. In this problem you will calculate a microlensing light curve. In the figure below, the dashed straight line represents the trajectory of a point source passing behind a point mass lens (the solid dot in the center). The circle indicates the Einstein radius. The x and y axes show the angular distance from the lens, measured in units of the Einstein radius: x/ E and y/ E . We will assume that the motion is in the x direction, so that y is constant and equal to the impact parameter . The figure shows the case of an impact parameter y = 0 . 5 E , but we will consider a range of values., but we will consider a range of values....
