Abstract
Open-access reader
An energy distribution for P Cyg (B1 Ia+) has been produced using UKIRT photometry and spectra, flux-calibrated IUE high-resolution spectra, Johnson and Mitchell 13-colour photometry and IRAS photometry. Infrared excesses due to free-free emission from the wind have then been derived and modelled.
A significance statement is not available in the OpenAlex record.
