New discovery may offer clues to ‘missing’ pulsars
Millisecond pulsars (MSPs) are evolved neutron stars with short spin periods that have gone through a long period of mass transfer in a low-mass X-ray binary phase. Globular clusters (GCs)—conglomerations of tens of thousands or millions of stars—are prolific environments for the formation of MSPs. However, in NGC 6397—one of two GCs closest to Earth—only one MSP had been identified until recently.
