Long-term variations of nonradial oscillations in a rapidly rotating early-type star (ζ oph)

E. Kambe; Hiroyasu Ando; Ryukou Hirata

We have been monitoring the line profile variations of a Be star, ζ Oph, since 1986 to investigate their connection to the Be-activity. From the period analysis of the variations, we have found that two modes detected in August 1989 are identical to the modes dominated in April 1987 and in May 1988 (Kambe et al. 1989. The amplitudes and the ratio of horizontal-toradial velocity amplitudes, of oscillations k, seem to vary from season to season, but it must be confirmed by further observations. The relation of the line profile variations to the Be-activity in this star is not yet clear.
