PULSARS

PULSARS

PULSARS are highly magnetized neutron star which is rotating at high speed .

It is White dwarf or neutron star which emits electromagnetic radiation. Pulsars have strong magnetic field which funnels jet out particles in form of radiation. This radiation can be detected only if radiation points towards earth. This particles create a beam of light.

Three distinct classes of pulsars are currently known , according to the source of the power of the electromagnetic radiation:

1.Rotation-powered pulsars, where the loss of rotational energy of the star provides the power,

2.Acceration power pulsars where gravitational potential energy of accerated matter is power source. 

3.Magnstars where decay of electromagnetic field of pulsar provide power. 

APPLICATIONS:                                    

pulsar are used to find unobservable celestial object known as neutron star which rotates near to speed of light.  

Milliseconds pulsar allowed to test        GENERAL RELATIVITY in conditions of high gravitational intensity.  Disturbances in the clocks will be measurable at Earth. A disturbance from a passing gravitational wave will have a particular signature across the ensemble of pulsars, and will be thus detected.
