Abstract

We present the first emission-line spectrum of β Pictoris, as revealed by the Far Ultraviolet Spectroscopic Explorer satellite. Broad emission lines due to highly ionized species, C III and O VI, are well detected above the very low continuum level. The mere presence of such lines in the β Pic spectrum is evidence of a complex stellar environment, including dense and hot regions. We argue that these spectral features may originate from a solar-like extended chromosphere or from magnetospheric accretion.
