| 内容記述 | Results are reported from a detailed analysis of Exosat observations of six hot He-rich white dwarfs belonging to, or related to, the spectroscopic subclass of PG1159 stars. These objects are thought to evolve directly from O VI type planetary nebulae nuclei and provide an important link in models of white dwarf evolution. When the Exosat data are compared with the predictions of an extensive grid of He-rich model atmospheres, it is possible to obtain temperature estimates for these stars that are much better constrained than previous attempts. |
