BD+02 2056 (original) (raw)

BD+02 2056, also known as WASP-84 is a G-type main-sequence star. Its surface temperature is 5350±31 K, and is slightly enriched in heavy elements compared to the Sun, with a metallicity Fe/H index of 0.05±0.02. It is rich in carbon and depleted of oxygen. BD+02 2056's age is probably older than the Sun at 8.5+4.1−5.5 billion years. The star appears to have an anomalously small radius, which can be explained by the unusually high helium fraction or by it being very young. A multiplicity survey did not detect any stellar companions to BD+02 2056 as at 2015.
