Hα variability of the B-type binary χ Aurigae.
RAJA T. and WOLF M.
Abstract (from CDS):
We report several new radial velocities of the early-type spectroscopic binary χ Aur derived from photographic and RETICON spectrograms. Improved orbital elements are computed and a new orbital period P=676days of this system is derived. The secondary component lines are invisible in the spectrum of the system with the supergiant primary. Spectral type of the secondary component is discussed. The description of the spectrum χ Aur in the wavelength range from 6300 to 6700Å is presented. Hα emission and its variability was discovered and Hα profile behaviour is described and analyzed.
