Swings between rotation and accretion power in a binary millisecond pulsar

Wieringa, M. H.; Campana, S.; Stella, L. +20 more

It is thought that neutron stars in low-mass binary systems can accrete matter and angular momentum from the companion star and be spun-up to millisecond rotational periods. During the accretion stage, the system is called a low-mass X-ray binary, and bright X-ray emission is observed. When the rate of mass transfer decreases in the later evolutio…
