Part of the Astrophysics and Space Science Library book series (ASSL, volume 95)


In the spectral range λλ5800–8750, HBV 475 shows important spectral variations between 1969 and 1974. Sometimes the “hot component” spectrum dominates (many emission lines), sometimes the “cool component” is preponderent (many molecular absorption TiO bands) (Andrillat 1973 — Andrillat, Houziaux 1976).
