Rapid photometric and spectroscopic variability of the Be star DX Eridani J/A+A/309/787 J/A+A/309/787 DX Eri variability Rapid photometric and spectroscopic variability of the Be star DX Eridani S Stefl L A Balona Astron. Astrophys. 309 787 1996 1996A&A...309..787S Line Profiles Photometry, uvby Stars, Be Stars, variable stars: activity stars: emission-line, Be stars: individual (DX Eri) We present results of nearly simultaneous monitoring of uvby light and HeI667.81nm line-profile variations of the equatorial Be star DX Eri in November 1991. They are analysed along with numerous uvby photometry in the period 1986-1995.
