P Cygni star | has prototype P Cygni | ![]() |
has definition A type of star whose spectrum shows strong emission lines, like those of the Be and Wolf-Rayet stars, with blueshifted absorption components which are presumed to come from an expanding shell of low-density matter. A P Cygni profile is taken as an indication of mass loss. | ![]() | |
has definition High-luminosity, early-type star, in which all lines have a P Cyg type profile (an emission component on the red side of the absorption line). | ![]() | |
