SPECTRAL LINE PROFILES VARIATIONS IN THE roAp STAR ALPHA CIRCINI

D. V. Alentiev

Анотація


We analyse behavior of the line profile variations of the brightest known roAp star αCircini based on the high-resolution spectra obtained with the HARPS spectrometer. The rapid variations of Nd and Pr line profiles are similar to other roAp stars.
