IRC+10420 - Another Eta Carinae?
Abstract
At long wavelengths (1-22μm) the infrared source IRC+ 10420 resembles very closely the peculiar object η Car. Photographic spectra of +10420 show it to be a very high luminosity star with spectral type about F8 or GO. This is remarkably similar to the cFS absorption-line spectrum reported for η Car in 1892
