Among them is a rare class of neutron stars called transitional millisecond pulsars that swing between two different observational states: an accretion-powered state in a low-mass X-ray binary system and a radio-powered millisecond pulsar state. So far, only three transitional MSPs have been confirmed to exhibit this switching behavior.<\/p>\n<p>In this study, Saptarshi Sarkar of the National Center for Radio Astrophysics in India and colleagues studied the third of these confirmed systems, PSR J1227\u22124853.
