Long-term Evolution in Ionization of Ejecta Illuminated by Eta Carinae

Long-term Evolution in Ionization of Ejecta Illuminated by Eta Carinae

Changes in the flux and spectrum of Eta Carinae ( η Car) since 1900 have been attributed to the evolution of the central binary by some. Others suggest evolution in the occulting ejecta. The brightness jump in the 1940s, which coincided with the appearance of narrow forbidden emission lines, may hav...
