HD 114762
HD 114762 is a binary star system approximately away in the constellation Coma Berenices. It consists of a yellow-white F-type main-sequence star and a red or brown dwarf companion approximately distant. Both are low-metal subdwarfs. A telescope or strong binoculars are needed to view the primary. had been used by scientists as a "standard star", one whose radial velocity is well established, but with the discovery of exoplanet its usefulness as a standard has been called into question.
Planetary
. However, misclassification of the star as a giant combined with an underestimation of the orbit of the Gamma Cephei binary, which implied the planet's orbit would be unstable, led some astronomers to suspect the variations were merely due to stellar rotation. The existence of the planet was finally confirmed in 2002.
- HD 114762 b: This object has a minimum mass 11 times the mass of Jupiter and has an 89-day orbit. At the time of its discovery it was regarded as a probable brown dwarf, although subsequently it
