Abstract:
Analysis of the surface composition of the suspected cool RV Tauri star CE Virginis 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 ε (Li) = 1.5 ± 0.2 indicates production of Li in the star. Near-infrared colours indicate sporadic dust formation close to the photosphere.
