A spectroscopic investigation of PCygni I . H and He I lines

  author={Francisco Najarro and D. John Hillier and Otmar Stahl},
We present a detailed spectroscopic analysis of the H and He i spectrum of the Luminous Blue Variable (LBV) P Cygni. The observational constraints for our investigation are given by the mean optical and near-IR spectra obtained by Stahl et al. (1993) and published UV, optical, IR and radio continuum measurements of the star. Within the parameter domain of interest we have investigated how line strengths, line shapes and the emergent energy distribution behave as a function of stellar parameters… CONTINUE READING
