Pulsar Spin

Definition

Pulsar Spin is how fast a newborn neutron star turns: a collapsing core keeps its angular momentum, so its period falls as the square of its radius, and a core turning once a day that shrinks to ten kilometres turns hundreds of times a second, sweeping its beams round the sky as a pulsar. The spin it keeps is the tidal spin every clump gathers, carried down to the smallest thing a star can leave. Formally, P_ns = P_c ยท (R_ns / R_c)ยฒ, where P_ns [๐•‹] is the neutron star's period, P_c [๐•‹] the core's period before collapse, R_ns [๐•ƒ] the neutron star's radius and R_c [๐•ƒ] the core's radius: [๐•‹] = [๐•‹]. It connects to Giant Phase, Halo Spin Parameter and Stellar Null Well.

Mathematical Expression

P_ns = P_c ยท (R_ns / R_c)ยฒ
