However, the nature of the orbiting object remains unknown, and previous studies have suggested that it may be a white dwarf ... with that of the radio pulsar," the researchers wrote in the ...

The white dwarf-pulsar binary system, PSR J1141-6545, discovered by the CSIRO's Parkes radio telescope. This material relates to a paper that appeared in the 31 Jan. issue of Science, published by ...

They assume that the white dwarf progenitor spun up the pulsar; however, they also take into account the possibility that the system might have formed in an exchange interaction. More information ...

Caption A 21-year study of a pair of ancient stars -- one a pulsar and the other a white dwarf -- helps astronomers understand how gravity works across the cosmos. The study was conducted with the ...

That made the discovery of something pulsar-like with an 18-minute period ... The team attribute this to a white dwarf so close to the red dwarf, and sufficiently faint, we can’t separate ...

Unexpectedly, the radio bursts aren’t from a pulsar but from a white dwarf, a dead star paired with a red dwarf, pulsing together in a stunning cosmic duet. Their orbital period — two hours ...

ESO’s Very Large Telescope (VLT) in Chile was used to measure the masses of both, the pulsar and the white dwarf. The William-Herschel Telescope (WHT) on La Palma was used to monitor the stability of ...

In X-Ray binary systems, a compact object (like a Black Hole, a Neutron Star or a White Dwarf) usually rotates about an optical star ... There exists an offset angle between the dipole magnetic axis ...
