| Abstract: | We show that the strong correlation observed between the braking indices (n) and the slowing-down ages (Τ) of pulsars is inconsistent
with counteralignment between their rotation and magnetic axes, but that the data on pulsars with positive braking indices
is consistent with alignment. Alternatively, slowing-down noise can quantitatively account for the data on all pulsars except
the Crab and the Vela, and so for the apparent|n| ∼ Τ2 correlation observed for the older pulsars. |
