Query: Non-spherical evolution of the line-driven wind instability   In this paper, we study the structure and stability of line driven winds
using numerical hydrodynamic simulations. We calculate the radiation force from
an explicit non-local solution of the radiation transfer equation, rather than
a Sobolev approximation, without restricting the flow to one-dimensional
symmetry. We find that the solutions which result have complex and highly
variable structures, including dense condensations which we compare to observed
variable absorption features in the spectra of early type stars.
