HD 77338

HD 77338 is a K-type subgiant star which has recently exhausted its hydrogen fuel and has started to expand. Its surface temperature is 5315 K. HD 77338 is enriched in its concentration of heavy elements compared to the Sun, with a metallicity Fe/H index of 0.16 but is much older at an age of 9.5 billion years.
HD 77338 is unusually enriched in heavy elements for a star of its age. The anomalously high abundance of ions of manganese may indicate the star has recently passed through the common shell stage (engulfed a planet).
Planetary system.
In 2012, one planet, named HD 77338b, was discovered by the radial velocity method on a tight orbit with uncertain eccentricity. Its equilibrium temperature is 954.8 K.
