Other Binary Systems
A whole range of differing two-body systems can occur, where a pulsar exists. Other than a double pulsar system, these systems also occur:
- A pulsar-white dwarf system; Such as the PSR B1620-26 binary star.
- A pulsar-neutron star system, such as PSR B1913+16.
- pulsar and a normal star; E.g, PSR J0045-7319, a system that is composed of a pulsar and main-sequence B star
A pulsar-black hole binary system is possible, but such a system is yet to be discovered. A Pulsar-black hole system could be an even stronger test of Einstein's theory of General Relativity, due to the immense gravitational forces exerted by both celestial objects. The Square Kilometre Array, a planned Radio Telescope due to be constructed in the southern hemisphere in 2012, will observe binary pulsar systems. It will also search for Pulsar-Black hole systems in order to test General Relativity.

Famous quotes containing the word systems:
“I am beginning to suspect all elaborate and special systems of education. They seem to me to be built up on the supposition that every child is a kind of idiot who must be taught to think.”
—Anne Sullivan (1866–1936)
