History and specifications[]

The temperature is between 10,000 and 28,000 Kelvins, generally referred to as being a blue star. (ST reference: Star Charts)

Type B0 V stars are 1,300 times brighter than Sol and have 17.5 times more mass. Their habitable zone ranges from 108-148 AU and are 20 million to 120 million years old. Type B5 V stars are 830 times brighter than Sol and have 8.2 times more mass. Their habitable zone ranges from 27.4-37.4 AU and are 300-800 million years old. (Decipher RPG module: Worlds)

The high levels of radiation emitted by the B-class star Bhea A of the Bhea star system led to the Federation rejecting a proposal to terraform the large class M planet Bhea I. (STO - Patrol the Vulcan Sector mission: "Bhea System Patrol")

In 2410, the Lukari star unexpectedly began to cease fusion and die down. The 27th century scientist Kal Dano used his invention, the Tox Uthat, a quantum phase inhibitor, to revive this star. The Tholians stole the Tox Uthat from Dano and used it to kill the star of the Na'kuhl system, setting in motion one of the key issues of the Temporal Cold War.
