Observations of stars, as well as theories of the structure of stars, suggest that it is impossible for a single star to have a mass of more than about 50 solar masses. Can this massive object be a single, ordinary star?

2 Hailstone Sequences [12 marks] A hailstone sequence is a sequence of integers found by applying the following rule: Hailstone Iteration: For an integer n in a hailstone sequence, the next item in the sequence is 3n + 1 if n is odd, or n / 2 if n is even. For example, the...

Consider the second-order system G(s) = 1/(s2 + 2 s + 1) . We would like to add a transfer function of the form D(s) = K(s+a)/(s+b) in series with G(s) in a unity-feedback structure. What are the constraints placed on K, a, and b so that the system is stable and type 1?
