The material falling into a black hole emits light in narrow wavelength regions forming emission lines which can be seen when the light is dispersed into a spectrum.
The meeting focused on active OB-stars as laboratories for the study of physical processes leading to stellar activity and the ejection of circumstellar material, particularly the orbiting disk that is central to rapidly rotating B-type stars with prominent emission lines of hydrogen in their spectrums (Be stars).
