In hot pursuit of the hidden companion of η Carinae: an X-ray determination of the wind parameters
Published online by Cambridge University Press: 26 May 2016
Abstract
We perform X-ray spectral fits to a recently obtained Chandra grating spectrum of η Carinae, one of the most massive and powerful stars in the Galaxy and which is strongly suspected to be a colliding wind binary system. The good fit that we obtain gives us further confidence in the binary hypothesis, and we find M ≈ 2.5 × 10–4 M⊙ yr–1 for the mass loss rate of η Car.
