white dwarf Astron.
A star that has exhausted most or all of its nuclear fuel and has collapsed to a very small size. Atoms are tightly packed together and a typical gravitational strength can be over 100 000 times the surface gravity of the Earth. Such a star is near its final stage of life.

WIMP Phys.
The acronym for Weakly Interacting Massive Particle. It is a type of 'exotic' non-baryonic, neutral sub-atomic particle that is weakly interacting. It can be massive, perhaps with a mass greater than the neutrons. These characteristics allow WIMPs to pass through any solid objects with negligible hindrance and the detection of such particles are very difficult. To date (as at 2002), WIMPs has yet to be detected and they are thought to be one of the possible condidate to be responsible for the missing matter (the dark matter) in the Universe.
