HAT-P-9 is a magnitude 12 F-type star approximately 1500 light-years away in the constellation Auriga.[1] A search for a binary companion star using adaptive optics at the MMT Observatory was negative.[2]

Naming

The star HAT-P-9 is named Tevel. The name was selected in the NameExoWorlds campaign by Israel, during the 100th anniversary of the IAU. The Hebrew word תֵבֵל tevel means "World" or "Universe".[3][4]

Planetary system

An exoplanet orbiting the star, HAT-P-9b, was discovered by the transit method on June 26, 2008. This is a low-density hot Jupiter, orbiting its star in just 3.9 days.[5]
