- Abstract
We studied the ? Scuti star 4 CVn through time-series spectroscopy1 , since photometry alone is insufficient to provide a unique solution to mode identification. However, the combination of multifilter photometry and high-resolution spectroscopy, similar to the data we obtained and analyzed, allows the necessary reliable mode identification. We have obtained 38 nights of time-series high-resolution spectroscopy at the 2.1 m telescope at McDonald Observatory for 4 CVn. We have done mode identification for five independent frequencies detected by spectroscopy, which were previously detected with photometric observations.
