Kritik
`This, then, is the first thorough, wide-ranging discussion of a group of stars which appears to be central to an understanding of evolution in the upper HR diagram. What's more, it's the best presented conference book I have ever seen since `camera-ready' became compulsory. Highly recommended.'

Autor

Kris Davidson is Professor of Astronomy at the University of Minnesota. He received his university degrees from the California Institute of Technology and Cornell University. His research has covered a diverse group of objects distinguished by their special characteristics -- QSO s, the Crab Nebula supernova remnant, X-ray sources and pulsars, and of course eta Carinae. He is the Principal Investigator on the Hubble Space Telescope Treasury Project on eta Carinae.
