In an article published in Nature on April 6, 2006, Deepto Chakrabarty et al. of MIT revealed that a circumstellar disk was discovered around the pulsar. This may prove that pulsar planets are common around neutron stars. The debris disk is likely to be composed of mainly heavier metals. The star had undergone a supernova event approximately 100,000 years ago. The disk orbits about 1.6 million kilometers away from the pulsar and probably contains about 10 Earth-masses of material.[1] This also marks the first time that a pulsar has been discovered with a debris disk orbiting it.[2]
In May 2022 the first study of IXPE has hinted the possibility of vacuum birefringence on 4U 0142+61[3][4]
