KELT-4Ab is an extrasolar planet that orbits the star KELT-4A, in the star system KELT-4. The planet is approximately away in the constellation of Leo. The planet was discovered by the Kilodegree Extremely Little Telescope (KELT).
Characteristics
The exoplanet was discovered by transit and is a Hot Jupiter planet orbiting a star in a triple star system, KELT-4. It is the fourth planet found in such a system. As KELT-4A is the brightest host (V~10) of a Hot Jupiter in a hierarchical triple stellar system found so far researchers expect it may be useful in learning more about inflated planets.
Star system
KELT-4 is a triple star system. KELT-4BC is a binary star system subcomponent of the triple, away from KELT-4A and the projected separation between KELT-4B and KELT-4C is .
