Scientific paper

Characteristics for a group of composite spectrum stars which have strong H alpha emission and peculiar satellite UV spectra are compared. Spectroscopic periods and photometric variability are discussed. Compared with normal noninteracting composite spectrum binaries, they exhibit excess flux in the middle UV region. This is believed to indicate the presence of an accretion disk.
