An
artist’s impression of the Circinus X-1 system showing the binary (double) star
system. Two stars orbit each other every 16.5 days in an elliptical orbit. The
small white sphere is the neutron star — an extremely dense and compact remnant
of an exploded star, only about 20 km in diameter.
The red sphere is an
ordinary star — the companion star in this system. When the two stars are at
their closest, the neutron star pulls material from its companion star.
An
accretion disk (the blue disk) forms around the neutron star, containing the
matter that is sucked from the ordinary star. Powerful jets of material (the
orange rays) then blast out from the neutron star at close to the speed of
light, causing powerful flares in radio frequencies.
