Animation of a Cataclysmic Binary
This video shows an interacting binary star system
known as a cataclysmic variable (CV) or cataclysmic binary. The larger star is a red
dwarf, a normal and very common star somewhat smaller, cooler and fainter than the
Sun. It is in orbit around a mu...

Cataclysm VI
A cataclysmic binary is a close-binary star system
consisting of red dwarf (bottom) in orbit around a white dwarf. The proximity of the
latter and its powerful gravity distorts the red dwarf. It gas flows away from it and
plunges towards and around t...

Cataclysmic Dawn
This is the same kind of binary star system (a
cataclysmic variable) as depicted Cataclysm III and VI this time seen from a cave on
a purely hypothetical, watery and rocky planet. Admittedly, though, such a situation
is highly unlikely to exist in re...

Cygnus X-1
Cygnus X-1 is a very famous x-ray binary star
system. It consists of a giant blue star (top) in orbit around what in all likelihood
is a – wait for it – black hole. The black hole steals gas from its giant
companion and that gas flows towards the...

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.

Planet of Kepler-35
Kepler-35 is a binary star system, around which
astronomers have found a so-called transiting circumbinary exoplanet, Kepler-35b.
That is, a planet which orbits both stars as if they were one. This image imagines
the view from the surface of a moon o...

Algol Animation With Graph
This is an animation of Algol showing how the light from the system varies as a
function of the orbit. Check the graph at the top right. There is a slight reduction
of light when the bigger but dimmer star (yellow) is behind the blue one, and a much
...

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 brightnes...

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 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...
