HR 1614 is a spectroscopic binary star system in the constellation Eridanus. (The information in the table is for the primary star.)

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 isabout 90% higher than the Sun. [cite journal | author=S. Feltzing, G. Gonzalez | title=The nature of super-metal-rich stars. Detailed abundance analysis of 8 super-metal-rich star candidates | journal=Astronomy and Astrophysics | year=2001 | volume=367 | issue=2 | pages=253–265 | url=http://www.aanda.org/articles/aa/full/2001/07/aah2231/aah2231.right.html | doi=10.1051/0004-6361:20000477 ] The activity cycle for this star is 11.1 years in length.

This system is a member of a moving group of at least nine stars that share a common motion through space. The members of this group display the same abundance of heavy elements as does HR 1614, which may indicate a common origin for these stars. The space velocity of this group relative to the Sun is 59 km/s. [cite journal | last = Eggen | first = O.
