Spectroscopic investigation of X Persei (= 2U 0352+30?).
Abstract
Radial velocity and line intensity measurements are reported from recent high dispersion spectrograms of X Persei. The binary interpretation of the previously reported s8o-day periodicity is discussed and revised orbital para1neters are presented. Line intensity changes occur but are not found to be correlated with this cycle. Rapid line profile changes have been observed with an Image Isocon camera. The emission line profiles are discussed in terms of binary model.
