X - ray binaries yog ib chav kawm binary hnub qub uas yog luminous nyob rau hauv X - rays . Cov X - rays yog tsim los ntawm cov teeb meem poob los ntawm ib feem, hu ua tus neeg pub dawb (feem ntau yog ib qho qub hnub qub ), mus rau lwm yam, hu ua accretor, uas yog heev compact: ib tug neutron hnub qub los yog lub qhov dub.

Yog li ntawd, yuav ua li cas lub hnub qub neutron nyob rau hauv ib tug binary system tsim x rays?

Cov x - rays yog emitted los ntawm cov pa uas poob rau hauv lub qhov dub uas tau ceev ceev thaum nws tau los ze rau Lub ntiajteb txawj nqus loj heev, thiab yog superheated raws li qhov tshwm sim - nws tawm hluav taws xob kub heev, x - rays.

Ib sab saum toj, dab tsi ua rau X-ray bursters? X - tawg tawg tshwm sim nyob rau hauv tsawg-ntau X - ray binary systems qhov twg lub hnub qub neutron thiab qis-ntau lub hnub qub nyob rau hauv lub orbit ib ncig. Rau ib X - tawg tawg , cov khoom compact yog lub hnub qub neutron uas accretes ib txheej txheej ntawm helium uas dhau los ua hluav taws kub los ua qhov tawg.

Ib yam li ntawd, tib neeg nug, X rays nyob rau hauv X ray binary zoo li Cygnus X 1 los ntawm?

Cygnus X - 1 . Cygnus X - 1 yog galactic X - ray qhov chaw nyob rau sab qaum teb constellation Cygnus . Cov X - ray qhov chaw ntseeg tau tias yog qhov stellar loj qhov dub, ib tsim los ntawm lub cev qhuav dej ntawm lub hnub qub loj txog 5 txog 6 lab xyoo dhau los.

binary hnub qub nyob ze npaum li cas?

Qee qhov, zoo li Alpha Centauri system, nruj binaries :ob ua hnub qub suav nrog Alpha Centauri yog kwv yees li 18 astronomical units (AU) sib nrug. (1 AU yog lub ntiaj teb qhov kev ncua deb mus rau lub hnub. Rau kev sib piv, Neptune qhov nruab nrab qhov deb yog li 30 AU.)
