PULSAR


en Limba Engleză Paperback – 25 sep 2014
A pulsar (short for pulsating radio star) is a highly magnetised, rotating neutron star that emits a beam of electromagnetic radiation. This radiation can only be observed when the beam of emission is pointing toward the Earth, much the way a lighthouse can only be seen when the light is pointed in the direction of an observer, and is responsible for the pulsed appearance of emission. Neutron stars are very dense, and have short, regular rotational periods.
