Entity: PULSAR
A pulsar is a celestial source of pulsating electromagnetic radiation, characterized by a short interval between pulses, believed to be a rotating neutron star.
PULSAR
Etymology
The term 'pulsar' is derived from 'pulsating star', reflecting the pulsating nature of the electromagnetic radiation emitted by these celestial objects.
Definition
A pulsar is a rapidly spinning neutron star that emits pulses of radiation, particularly radio waves, with remarkable regularity. These objects are characterized by their compact size and intense magnetic fields.
Historical Context
Pulsars were first discovered in 1967 by astronomers Jocelyn Bell Burnell and Antony Hewish, revolutionizing our understanding of neutron stars and their behavior.
Cultural Significance
Pulsars have become key objects of study in astrophysics, providing insights into extreme physical conditions and serving as cosmic laboratories for testing fundamental physics theories.
Related Concepts
Pulsars are closely related to neutron stars, black holes, and other compact astronomical objects that exhibit unique electromagnetic properties.
