text: We also know that pulsars are very small and so they must be very dense.
text: In an 'accreting' neutron star system, a pulsar (a dense remnant of an old star) strips material away from a nearby star, forming an accretion disk of material spiralling in towards the pulsar, where it releases extraordinary amounts of energy -- about the total energy output of the sun in 10 years, over the period of a few short weeks.
text: By general definition, a pulsar is a small dense star (believed to be a neutron star) that emits mostly brief but intense bursts of electromagnetic radiation.
text: The system was discovered in 2014, and comprises a pulsar, or neutron star – a super-dense object with, thus, extremely strong self-gravity – and two white dwarf stars.
