Abstract
The purpose of this article is to find out sharp estimates for the first eigenvalue of the stability operator for compact surfaces with constant mean curvature immersed into a Riemannian 3-manifold having a nowhere vanishing closed conformal vector field, and characterize the cases where the estimates are reached.
