Planetary Nebulae: Central Stars, Planetary Nebulae: Temperatures, Planetary Nebulae: Luminosities
Scientific paper
The position of the central stars of planetary nebulae on the T/L diagram provides an important test of the stellar evolution theory. The authors present, at first, a brief review of the recent works presented on this subject. The confrontation of observational results with theoretical models allows to precise the range of the masses of the central stars, which represents the main parameter governing their evolution. In the second part, they present the results of their new spectrophotometric survey; they have computed temperatures and luminosities of the central stars, using newly derived observational parameters and statistical distances. Taking into account the limitation both on their observations and on the used methods, the T/L diagram obtained enables them to estimate the range of the mass distribution.
