Eta Carinae and the Supernova Impostors
ISBN: 9781461422747 / Angielski / Twarda / 2012 / 330 str. Termin realizacji zamówienia: ok. 20 dni roboczych. 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...

Physics of Luminous Blue Variables: Proceedings of the 113th Colloquium of the International Astronomical Union, Held at Val Morin, Quebec Province, Canada, August 15–18, 1988
ISBN: 9789401069557 / Angielski / Miękka / 2011 / 328 str. Termin realizacji zamówienia: ok. 20 dni roboczych. A strange field of speculation is opened by this phenomenon ...here we have a star fitfully variable to an astonishing extent. and whose fluctuations are spread over centuries. apparently in no settled period. and with no regularity of progression. What origin can we ascribe to these sudden flashes and relapses? What conclusions are we to draw as to the comfort or habitability of a system depending for its supply of light and heat on so uncertain a source? -- J. F. W. Herschel! We can imagine, at least, that the study of Luminous Blue Variable stars began as the official court astrophysicists...
