Scientific paper

Systematic spectral and photometric observations have been made of the object MWC560. Spectra of the hydrogen absorption Balmer lines indicate that some components have radial velocities as large as -6000 km/s. The profiles are complex, showing pronounced variability on timescales of a few days. The V-band brightness was seen to change by a few tenths of a magnitude. It is speculated that MWC560 may be a binary system containing a red giant and a compact companion and exhibiting jetlike ejections along the line of sight.
