Celestial objects emitting intense X-rays are generally called X-ray sources. In particular, stars emitting X-rays are called X-ray stars.
Most of X-ray stars are close binary systems,
which consist of a normal star and a compact object,
such as a neutron star or a black hole.
These are called X-ray Stars in Close Binary or simply X-ray Binaries.
X-ray binaries are classified into X-ray bursters, X-ray pulsars, X-ray novae, and so on.
強いX線を放射している天体をX線星(X-ray star)と呼びます.
X線星の多くは,
中性子星やブラックホールなどのコンパクト星と通常の恒星からなる近接連星系で,
それらを近接連星型X線星とか,たんにX線連星と呼ぶこともあります. The kind and structure of the X-ray Binary |
