Analysis of the surface composition of the suspected cool RV Tauri star CE Vir shows no systematic trend in depletions of elements with respect to condensation temperature .
However , there is a significant depletion of the elements with respect to the first ionization potential of the element .
The derived Li abundance of log \epsilon ( Li ) = 1.5 \pm 0.2 indicates production of Li in the star .
Near infrared colours indicate sporadic dust formation close to the photosphere .
