…X-ray binaries can be classified as follows. Type I X-ray stars are often observed as X-ray pulsars. They are X-ray sources that pulsate with a specific period, just like radio pulsars. However, while the period of radio pulsars is shorter than 2 to 3 seconds, some with periods ranging from less than 1 second to as long as 830 seconds have been found. … From [Pulsar]…Currently, several hundred pulsars have been found in the Milky Way Galaxy. So far, we have been talking about radio pulsars, which emit pulses in radio waves, but there are also X-ray pulsars, which emit pulses in X-rays. X-ray pulsars are close binary star systems consisting of a neutron star and an ordinary star. When gas ejected from the ordinary star falls onto the magnetic poles of the neutron star, gravitational energy is released, and X-rays are emitted in a pulsed form. … *Some of the terminology that refers to "X-ray pulsar" is listed below.

…X線連星はかりに次のように分類することができる。 第1種X線星はしばしばX線パルサーとして観測されているものである。これは電波で観測されるパルサーと同じように固有の周期で脈動するX線源であるが,電波のパルサーの周期が2~3秒より短いのに対して,周期は1秒以下のものから長いもので830秒に及ぶものが見つかっている。… 【パルサー】より…現在,パルサーは銀河系内で数百個見つかっている。これまでの話は電波でパルスを出す電波パルサーについてであったが,これ以外にX線でパルスを出すX線パルサーもある。X線パルサーは,中性子星とふつうの星からなる近接連星系で,ふつうの星から放出されたガスが中性子星の磁極に降り積もるとき重力エネルギーが解放され,パルス状にX線が放射される天体である。… ※「X 線パルサー」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
