Class T planets represent the upper limit of planetary mass. Most exist in the cold zone of star systems and are very similar to class S and J planets. However, class T planets occasionally form stars within the system's hot zone. If they are massive enough (13 times more massive than Jupiter), deuterium ignites nuclear fusion in the nucleus and the planet becomes a red dwarf, creating a binary star system.
