In astronomy, Pulsar, Binary, Dwarf and Red Giant are all types of what?
Binary pulsar Binary pulsar A binary pulsar is a pulsar with a binary companion, often a white dwarf or neutron star. (In at least one case, the double pulsar PSR J0737-3039, the companion neutron star is another pulsar as well.) Binary pulsars are one of the few objects which allow physicists to test general relativity because of the strong gravitational fields in their vicinities. Although the binary companion to the pulsar is usually difficult or impossible to observe directly, its presence can be deduced from the timing of the pulses from the pulsar itself, which can be measured with extraordinary accuracy by
Spacecraft in Red Dwarf alternate universe version to "Blue Midget" in Kochanski's dimension. The "White Midget" model used for "Ouroboros" was actually a converted "Blue Midget" model, last used in Series III. Mike Tucker and freelancer Alan Brennan refurbished the original model, adding a nose-cone, wings and back engines and repainted it. An unnamed, white ship would appear as the Canaries' primary transport in Series VIII. White Giant is a shuttlecraft on "Red Dwarf" that only features in the "Red Dwarf" novels and is never mentioned in the television series. It's never explained what the craft looks like. In the second "Red Dwarf" novel,
