In 1965 Fritz Zwicky proposed a class of supernovae that he called
"Type V", described as "excessively faint at maximum". There were
only two members, SN1961v and Eta Carinae. We now know that Eta
Carinae was not a true supernova, but if it were observed today in
a distant galaxy we would call it a "supernova impostor". 170 years
ago it experienced a "great eruption" lasting 20 years, expelling
10 solar masses or more, and survived. Eta Carinae is now
acknowledged as the most massive, most luminous star in our region
of the Galaxy, and it may be our only example of a very massive
star in a pre-supernova state. In this book the editors and
contributing authors review its remarkable history, physical state
of the star and its ejecta, and its continuing instability.
Chapters also include its relation to other massive, unstable
stars, the massive star progenitors of supernovae, and the "first"
stars in the Universe.
