A 20-year follow-up of CH+, CH, and CN absorption lines

Aims. The runaway star AE Aur (HD 34078) is currently crossing the molecular cloud associated with the IC 405 nebula. Previous observations have revealed large time variations of CH+ and CH absorption lines in AE Aur spectra, as the line of sight drifts through the foreground gas at a rate of about...
