  skos:definition "Un pulsar est un objet astronomique produisant un signal périodique allant de l'ordre de la milliseconde à quelques dizaines de secondes. Ce serait une étoile à neutrons tournant très rapidement sur elle-même (période typique de l'ordre de la seconde, voire beaucoup moins pour les pulsars milliseconde) et émettant un fort rayonnement électromagnétique dans la direction de son axe magnétique. (Wikipedia, L'Encylopédie Libre, <a href=\"https://fr.wikipedia.org/wiki/Pulsar\" target=\"_blank\">https://fr.wikipedia.org/wiki/Pulsar</a>)"@fr, "A pulsar (from pulsating radio source) is a highly magnetized rotating neutron star that emits beams of electromagnetic radiation out of its magnetic poles. This radiation can be observed only when a beam of emission is pointing toward Earth (similar to the way a lighthouse can be seen only 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. This produces a very precise interval between pulses that ranges from milliseconds to seconds for an individual pulsar. Pulsars are one of the candidates for the source of ultra-high-energy cosmic rays.
