WASP-76, also known as BD+01 316, is a yellow-white

main sequence In astronomy, the main sequence is a classification of stars which appear on plots of stellar color index, color versus absolute magnitude, brightness as a continuous and distinctive band. Stars on this band are known as main-sequence stars or d ...

s was reported in 2014. After about five billion years, WASP-76 has expanded and become more luminous than at the start of its

life, but most probably has not yet reached the

subgiant branch A subgiant is a star that is brighter than a normal main-sequence star of the same spectral class, but not as bright as giant stars. The term subgiant is applied both to a particular spectral luminosity class and to a stage in the evolution of ...

The "hot Jupiter" class planet

WASP-76b WASP-76b is an exoplanet classified as a Hot Jupiter. It is located in the constellation Pisces and orbits its host star, WASP-76, at a distance of approximately . Its orbital period is approximately 1.8 days, and its mass is about 0.92 times th ...
