Be X-Ray Binary
Here is a different kind of x-ray binary. In the
foreground (top) is a hot star called a Be star. It spins so quickly that it is
surrounded by a circumstellar disc of matter, flung off via centrifugal force. The Be
star is in orbit around a tiny and ...

Binary Asteroid 90 Antiope
This is an impression of the binary asteroid 90
Antiope, which orbits in the main part of the outer asteroid belt. Each asteroid is
about 86 km across, orbiting its partner from a distance of 170 km and with a period
of 16.5 hours. Binary asteroids a...

Binary Sunset
In this image I imagine an Earth-like world in orbit around not a single star but a
close binary. What beautiful sunsets could be
witnessed from this world. In the sky I have added a giant satellite, its night side
illuminated by cities, betraying in...

High-Mass X-Ray Binary
This is an animation of a high-mass x-ray binary, in
which a giant blue star is in orbit around a compact companion – sometimes a
neutron star and sometimes a black hole. The giant star is distorted owing to its
proximity to its highly compact part...

Low-Mass X-Ray Binary II
This image shows a low-mass x-ray binary star seen
from a nearby, hypothetical asteroid field. The system consists of a red dwarf
(bottom) which is losing its atmosphere to a black hole via an accretion disc....

W UMa Binary (Contact Phase)
W UMa (W Ursae Majoris) is the prototype of a class of interacting binary stars in which each member reaches out to touch the
other. The stars are so close to one another that the gravity of each visibly
distorts the other into a balloon shape. This ...

W UMa Binary (Over-Contact Phase)
W UMa (W Ursae Majoris) is the prototype of a class of interacting binary stars in which each member reaches out to touch the
other. The stars are so close to one another that the gravity of each visibly
distorts the other into a balloon shape. This ...

Binary Black Hole Merger
Illustration of two black holes orbiting each other in a combined accretion disc.
Eventually the black holes will merge, an event that will produce gravitational
waves. Gravitational waves are a prediction of Einstein's theory of general
relativit...

Extrasolar Binary
This was a commission for Scientific American, in their September 2000 edition. It
was to illustrate an article about finding extrasolar planets via occultation – by
detecting the dip in light levels as the planets transit in front of their stars. ...

Algol
Algol, also known as Beta Persei in the constellation Perseus, is the prototype of a
class of interacting binary stars which differ from
cataclysmic binaries. It was the first eclipsing binary ever found. Viewed from Earth, Algol varies its
