| Research Abstract |
We investigate the properties of supernova remnants that exhibit recombination X-rays, and look into the origin of the relevant recombining plasma in their evolution. It is found that a core-collapse supernova surrounded by the anisotropic stellar wind matter can produce recombination X-rays due to rapid cooling in the inner part of the remnant and form a synchrotron-radio outer shell, as observed, when the blast-wave breaks out of the wind matter into the rarefied interstellar medium.
