Creators

Description

Radial-velocity measurements of X Persei of spectra obtained from 1920 to 1974 reveal a probable periodicity of about 584 days. The broad Balmer absorption lines and the emission peaks move in antiphase and suggest the existence of a companion of mass at least 30 M0. Si bjert headings: Be stars - binaries - massive stars - X-ray sources
