After eliminating other possible causes of this drift, the scientists concluded that it was the result of frame dragging: The method the rapidly spinning white dwarf pulls on space-time has actually triggered the pulsar’s orbit to change its orientation gradually over time. Need more space?
A pulsar is a fast-spinning neutron star that gives off radio waves along its magnetic poles. After getting rid of other possible causes of this drift, the researchers concluded that it was the result of frame dragging: The way the quickly spinning white dwarf pulls on space-time has triggered the pulsar’s orbit to change its orientation gradually over time.”Systems like PSR J1141-6545, where the pulsar is more youthful than the white dwarf, are quite unusual,” Venkatraman Krishnan stated.
