Abstract
We analize a series of high-resolution optical spectroscopic observations of the eclipsing binary R Arae obtained at CTIO, Chile that cover more than an orbital cycle. The spectra show both absorption and emission features that follow the movement of the brighter component of the system and display changes throughout the cycle of light variations. We study the behavior of the stronger features with the purpose of shading light on the phenomena that are taking place in the circumstellar material.
