Initial estimates of the system's age based on the rotation of the star suggested the object was around 4 Jupiter masses. Other properties of the star indicate that it is likely several billions of years old, resulting in higher mass estimates for the companion. The rapid rotation may have been caused by the star engulfing a hot Jupiter. imaging 17/12/04 2013 Gliese504 This is an actual image of the exoplanet Gliese 504 b and its host star.
