Pulsar in the constellation Camelopardalis
PSR B0329+54 is apulsar approximately 3,460light-years away in theconstellation ofCamelopardalis . It completes one rotation every 0.71452[ 2] seconds and is approximately 5 million years old.[ 2]
The emissions of this pulsar and theVela Pulsar were converted into audible sound by the French composerGérard Grisey , and used as such in the pieceLe noir de l'étoile (1989–90).[ 3] [ 4] [ 5]
In 1999, twoexoplanets were announced to be orbiting the pulsar (being classified aspulsar planets ). Later observations did not support this conclusion.[ 6] [ 2] [ 7] [ 8] [ 9]
