Test Candidate J1937+2134





Double Pulses?

The axis on this pulsar is tilted in a way that the rotation axis is pointed towards but slightly off to one side. So when it rotates we pick up the inter-pulse.

What is a binary pulsar?



A binary pulsar is a pulsar with a companion (another pulsar) orbiting around each other

  • A binary pulsar is a pulsar with a companion (another pulsar) orbiting around each other

  • Often it is a white dwarf or a neutron star

  • The companion of the pulsar is very difficult to discover

  • The easiest way to discover one is by using a radio telescope because pulsars emit impulses that are extremely regular and stable in the radio wave region

  • We find binary pulsars when the GBT picks up both signals and we can find a huge change in the period over time
