The period between pulses from a particular pulsar increases slowly with time.This implies that the:
A) pulsar's magnetic axis is shifting with time.
B) pulsar is moving away from the observer.
C) pulsar has a binary companion.
D) pulsar's radiation carries angular momentum.

Question

Quizplus · Accepted Answer

The increase in the period between pulses from a pulsar indicates that the pulsar is losing rotational energy, likely due to the emission of radiation that carries away angular momentum. This process causes the pulsar to spin more slowly over time, leading to an increase in the period between pulses.
