HD 114729

HD 114729 is a yellow dwarf star located approximately 122 light-years away in the constellation Centaurus. It is slightly smaller and less massive than our Sun, with a spectral type of G0V. HD 114729 is known for being orbited by a brown dwarf companion, HD 114729 b.

HD 114729 b, discovered in 1989, was one of the first substellar objects discovered orbiting a sun-like star. Its mass is estimated to be at least 11 times that of Jupiter, placing it at the border between a large planet and a small brown dwarf. The companion orbits HD 114729 at a relatively close distance, with an orbital period of roughly 84 days.

The system has been the subject of ongoing research to understand the formation and evolution of brown dwarfs and planetary systems. The relatively small size and close proximity of HD 114729 b make it a valuable target for studying the atmospheres and characteristics of these intriguing objects. The star itself is also studied to better understand the influence of its companion on its properties and activity.
