Simultaneous uvbyβ photometry and Hα spectroscopy of Be stars in open clusters
Published online by Cambridge University Press: 26 May 2016
Extract
The usual methods of spectral clasification, equivalent widths of Balmer lines or photometric calibrations are not suitable for the determination of the astrophysical parameters of the underlying star in Be-type objects. The spectrum is distorted by the circumstellar envelope lines, while the contribution of the envelope continuum radiation contaminates the photometric indices.
