HR 1614
Encyclopedia
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 is about 90% higher than the Sun. 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. The estimated age of this group is 2 Gyr.
Constellation
In modern astronomy, a constellation is an internationally defined area of the celestial sphere. These areas are grouped around asterisms, patterns formed by prominent stars within apparent proximity to one another on Earth's night sky....

Eridanus (constellation)
Eridanus is a constellation. It is represented as a river; its name is the Ancient Greek name for the Po River. It was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and it remains one of the 88 modern constellations. It is the sixth largest of the modern...

Helium
Helium is the chemical element with atomic number 2 and an atomic weight of 4.002602, which is represented by the symbol He. It is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas that heads the noble gas group in the periodic table...

In astronomy and physical cosmology, the metallicity of an object is the proportion of its matter made up of chemical elements other than hydrogen and helium...
