On the timing history of PSR B1509 – 58
The measurement of the third frequency derivative of PSR B1509–58 reported by Kaspi et al. is consistent with a constant magnetic moment. If a more accurate, stable measurement can be made, it should be possible to test directly models in which the magnetic moment varies.
