For a exercise I need to find out how the amount of nuclide produced by s- and r-process changed over time and I also need to draw a schematic diagram of the s-/r-ratio vs. time from 13.6 Ga till today and explain my reasoning. I searched for an answer in my lecture notes and also the lecture but I can't find a solution for this problem. Can somebody help me out where I could find an answer for this?

    That's a rather broad question! Since this is for an exercise, you should include in your question your thoughts on this topic. Think about what has changed over time that could affect the amount of nuclides produced by the s- & r-processes. There are some useful hints in the first two paragraphs of https://en.wikipedia.org/wiki/S-process – PM 2Ring Jan 25 '20 at 17:02

    Homework question. You need to think about what processes/types of stars produce each type of element, when the progenitors of these were born, how long they lived, and what the star formation rate is as a function of time. – ProfRob Jan 26 '20 at 19:23
