Rapid Hα Variability in Phi Persei
Abstract
A search for rapid variability of H-alpha with a time resolution from 30 to 45 seconds is performed for Phi Per. In total, 42 spectra in H-alpha were obtained during three nights. Results show the presence of rapid irregular variability (time scale of a few minutes) of the equivalent width of the H-alpha line in Phi Per.
