Abstract: |
We investigate the oscillation properties of ε Cep using a series of specialized techniques designed to extract and analyze time variations in absorption line profiles. To obtain the necessary temporal coverage for this investigation, multi-site observations were collected at 3 sites (China, France, Arizona) all equipped with high-resolution echelle spectrographs. From these observations, we find evidence for a very rich spectrum of modes in ε Cep. |
