Structure and evolution of central stars of Planetary Nebulae [PDF]
Symposium - International Astronomical Union, 1997 In this review a critical examination of our present knowledge about the structure and evolution of central stars of planetary nebulae is presented. In particular, the still enigmatic origin of the Wolf-Rayet central stars is addressed, too. Some directions for future work are given at the end.
