[2] The photosphere is radiating energy at an effective temperature of 5,614 K.[7] It has a higher than solar metallicity – a term astronomers use to describe the abundance of elements other than hydrogen and helium.
[9] The discovery of a planetary system orbiting HD 134606 was announced in 2011 following an eight-year survey carried out at the La Silla Observatory in Chile.
Applying a Keplerian fit to the data suggests the presence of three planets in moderately eccentric orbits.
The five planets range from super-Earth to super-Neptune mass, and the outermost, HD 134606 d, is a small gas giant orbiting within the habitable zone that may be a candidate for future space-based direct imaging missions.
A long-period radial velocity trend was also detected, suggesting the presence of a distant sixth substellar companion of some kind.
