NASA-JAXA XRISM Mission Sees Pulsar Accreting Companion's 'Wind'

This artist’s concept of the BP Crucis system follows the pulsar on a passage through the dense stream of plasma flowing from its companion, a blue hypergiant 40 times the Sun’s mass. During each four-day passage, the pulsar’s X-ray brightness flares up as it pulls in some of the gas. At first, the gas forms a messy, turbulent accretion disk around the pulsar, and plasma spirals down to it. But as the pulsar moves deeper into the stream, there’s not enough angular momentum to support the disk, and it breaks up. At this point, plasma falls straight onto the pulsar. Later, as the pulsar nears the end of its passage, a messy accretion disk rebuilds, this time spinning in the opposite direction of the earlier disk.
