The Position of the Central Stars of PN on the HR Diagram
Published online by Cambridge University Press: 19 July 2016
Extract
Central stars can be placed on the HR diagram if their effective temperature (Teff) and radii are known. Knowledge of the radius can sometimes be replaced by another indication of the luminosity. The distance, which always plays an important, really critical role, is not well known. This is the essential reason that there is so much uncertainty about the position on the HR diagram.
