High Resolution Spectroscopy of the high galactic latitude RV Tauri star CE Virginis
read the original abstract
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.

Spectroscopy of a sample of RV Tauri stars without IR excess
New high-resolution abundances for five RV Tauri stars without IR excess; V457 Cyg shows depletion and V894 Per appears to be a binary, not an RV Tauri star.
