Study of line-profile variations in the spectrum of Oph during the May/June 04 MOST satellite campaign

Abstract

In support to the 3-week photometric campaign of ALPHA Oph by the Canadian MOST satellite, high S/N spectra of ALPHA Oph were obtained over a similar time interval. Results of the time-series analysis of the He I LAMBDA 4922 line based on local radial velocities are presented.
