We examine models in which the dark energy density increases with time (so that the equation-of-state parameter w satisfies w < -1), but w approaches -1 asymptotically, such that there is no future singularity. We refine previous calculations to determine the conditions necessary to produce this evolution. Such models can display arbitrarily rapid expansion in the near future, leading to the destruction of all bound structures (a "little rip"). We determine observational constraints on these models and calculate the point at which the disintegration of bound structures occurs. For the same present-day value of w, a big rip with constant w disintegrates bound structures earlier than a little rip.

- Viscous Cosmology for Early- and Late-Time Universe (2017, methodology): “Amongst them, the Little Rip scenario proposed by Frampton et al. [132, 133] (for nonviscous fluids) is an elegant solution, which we will consider in more detail in this subsection, generalized to the case of viscous fluids.”
