The Trivoli pulsar was a celestial object located near the planet Tulgana IV.
In 2380, the USS Cerritos passed near the pulsar at 0800 hours. Ensigns D'Vana Tendi and Sam Rutherford watched it on a PADD together in a Jefferies tube. (LD: "Envoys")
A year later, Tendi and Rutherford revisited that Jefferies tube and reminisced about the pulsar. (LD: "First First Contact")
