Profiles of absorption lines toward the star located behind the southern lobe of the CK Vul outflow. The left panel shows circumstellar absorption of Li I and Ca I in the circumstellar gas (upper lines) and interstellar features (lines shifted down by 0.3). Note the different central velocities of the two groups. The right panel shows features of the Na I doublet and Hα that combine circumstellar, interstellar, and photospheric absorption. The filled cyan area shows absorption common for both lines of the blending Na I doublet and approximates the shape of the intrinsic Na I absorption.
