ultra-hot jupiters

A form of ultra-hot jupiter — A giant planet, of similar mass to that of Jupiter, which orbits close enough to its sun to become tidally locked, and whose day-side atmosphere has therefore heated up so much, as to break apart most molecules, leaving atomic gas. The day-side atmosphere has the temperature and spectral characteristics of a star's surface.
