The X-ray properties of Eta Carinae during its 2020 X-ray minimum

A Kashi, DA Principe, N Soker… - The Astrophysical …, 2021 - iopscience.iop.org
The massive binary system Eta Carinae is characterized by intense colliding winds that form
shocks and emit X-rays. The system is highly eccentric (e≃ 0.9), resulting in modulated X-ray …

Explaining the early exit of Eta Carinae from its 2009 X-ray minimum with the accretion model

A Kashi, N Soker - The Astrophysical Journal, 2009 - iopscience.iop.org
We use the accretion model to explain the early exit of η Car from its 2009 X-ray minimum. In
the accretion model, the secondary star accretes mass from the primary wind near periastron …
