Orbital period-Hα correlation in Be star/X-ray binaries?
APPARAO K.M.V.
Abstract (from CDS):
Reig, Fabregat & Coe (1997A&A...322..193R) plotted the equivalent width of Hα emission against the orbital period for several Be star/X-ray binary systems, and find a correlation. If instead of the equivalent width, which is a relative quantity, the luminosity of Hα emission, which is an absolute quantity, is used the correlation is not found.
