timing noise

Timing noise refers to unpredictable variations or irregularities in the rotation of a pulsar or neutron star. While these stars generally spin at incredibly consistent rates, small, random fluctuations can occur due to internal processes or external influences. This results in tiny differences in the timing of the star's emitted signals, making their rotation seem slightly irregular over time. Timing noise is important because it affects precise measurements used in astrophysics, such as studying gravitational waves or testing fundamental physics. It reflects the complex, dynamic behavior of these dense, rotating objects beyond their simple, steady spin.
