Given a probability measure μ on the unit circle T, we study paraorthogonal polynomials B_{n}(^{.},w) (with fixed w ∈ T) and their zeros which are known to lie on the unit circle. We focus on the properties of zeros akin to the well known properties of zeros of orthogonal polynomials on the real line, such as alternation, separation and asymptotic distribution. We also estimate the distance between the consecutive zeros and examine the property of the support of μ to attract zeros of paraorthogonal polynomials.
