PSR B0329+54 is a pulsar approximately 3,460 light-years away in the constellation of Camelopardalis. It completes one rotation every 0.71452[2] seconds and is approximately 5 million years old.[2]

The emissions of this pulsar and the Vela Pulsar were converted into audible sound by the French composer Gérard Grisey, and used as such in the piece Le noir de l'étoile (1989–90).[3][4][5]

Planetary system

[edit]

In 1999, two exoplanets were announced to be orbiting the pulsar (being classified as pulsar planets). Later observations did not support this conclusion.[6][2][7] More recently, a 2017 analysis indicates that a different long-period pulsar planet remains a possibility,[8] but this was subsequently challenged as well.[9]
