HR 1614 is a spectroscopic binary star system in the constellation Eridanus. It is considered a metal-rich dwarf star, which means it displays an unusually high portion of elements heavier than helium in its spectrum. This metallicity is given in term of the ratio of iron to hydrogen, as compared to the Sun. In the case of HR 1614, this ratio is about 90% higher than the Sun. The activity cycle for this star is 11.1 years in length.
