Abstract

We report attempts to model the observed line-profile variations (lpv) of λ Eri during a productive spectroscopic and photometric campaign in 1994 November. We find that none of the nonradial pulsation spheroidal modes with m = −1 — −3 could explain the lpv associated with the dominant 16.9 hr period since the horizontal velocity components and the temperature variations dominate the lpv for such modes. In contrast, certain tesseral toroidal modes can reproduce the observed lpv well both for the main 16.9 hr period and the 6.45 hr period.
