A Spectroscopic Search for Non-Radial Pulsations in the Delta Scuti Star Gamma Bootis

High‐resolution spectroscopic observations of the rapidly rotating δ Scuti star γ Bootis have been carried out in 2005, over six consecutive nights, in order to search for line‐profile variability. Time‐series, consisting of flux measurements at each wavelength bin across the Ti ii 4571.917 Å line profile as a function of time, have been Fourier analysed. The results confirm the early detection re...
