Trilithium weapon
A trilithium weapon was a weapon that utilized trilithium as an explosive agent. It was capable of stopping all nuclear fusion within a star, causing an instant supernova.

In 2371, Dr. Tolian Soran managed to perfect the weapon, using trilithium stolen from the Romulans by the Duras sisters, Lursa and B'Etor. The sisters intended to use the weapon to conquer the Klingon Empire, after the failure of their attempt to seize control of it in 2368. 

However, Soran's only intended use for the weapon was to change the course of the energy ribbon that allowed entry into the Nexus. To achieve this, he used the weapon to detonate the Amargosa star and then planned to destroy the Veridian star. He briefly succeeded to Nexus, but was stopped by Captains Jean-Luc Picard and James T. Kirk. ()  

The Changeling  created a trilithium weapon composed of trilithium, tekasite, and protomatter designed to destroy the Bajoran sun, and thus Bajor, Deep Space 9, and a combined Federation-Klingon-Romulan fleet that had been lured to the mouth of the Bajoran wormhole in anticipation of a Dominion invasion. His attempt was stopped by the , which hurled his stolen  runabout USS Yukon away from the sun, causing the bomb to detonate harmlessly in space. ()
