'''HD 132563''' is a [[triple star]] system in the constellation [[Boötes]]. The two resolvable components of this system are designated HD 132563A and HD 132563B. The primary star, HD 132563A, is actually a [[spectroscopic binary]] with a period of more than 15 years and an [[orbital eccentricity]] of greater than 0.65. The smaller member of this tightly orbiting pair has about 55% the [[Solar mass|mass of the Sun]].<ref name=arxiv1107.0918/>

HD 132563 can be resolved into two stars with a separation of {{val|4.1|ul="}} and magnitudes of 9.0 and 9.5.<ref name=msc/> These two stars have almost identical distances and [[proper motion]]s and are widely accepted to form a binary system with a separation of about {{val|400|ul=au}}.<ref name=arxiv1107.0918/>

The primary, component A, consists of a star slightly more massive and hotter than the sun and an unseen companion with a mass of about {{solar mass|0.6|link=y}}. These two stars circle each other in a highly eccentric orbit with separations varying between {{val|2.1|u=au}} and {{val|27.5|u=au}}<ref name=msc/> Based on evolutionary modelling and isochrone fitting, the primary is right at the end of its main sequence life and starting to expand into a [[subgiant]].<ref name=arxiv1107.0918/>

Component B is too far from the primary for orbital motion to have been observed, but it is estimated that an orbit would take about 5,000 years. It is [[main sequence]] star very similar to the Sun.<ref name=arxiv1107.0918/>

A further 9th-magnitude star 65" from the primary is listed as component C in the [[Washington Double Star Catalog]],<ref name=wds/> but is much further away from us than the triple system.<ref name=dr3c/>

==Planetary system== Based upon radial velocity variations of HD 132563B, the presence of an ordinary [[giant planet]] has been inferred by S. Desidera ''et al.'' (2011). This object is orbiting the star with a period of 1,544 days, at a distance of about 2.6 [[Astronomical unit|AU]], and with an orbital eccentricity of 0.22.<ref name=arxiv1107.0918/> {{OrbitboxPlanet begin | table_ref = <ref name=arxiv1107.0918/> }} {{OrbitboxPlanet | exoplanet = b | mass = {{val|p=≥|1.49|0.09}} | semimajor = {{val|2.62|0.04}} | period = {{val|fmt=commas|1544|34}} | eccentricity = {{val|0.22|0.09}} }} {{Orbitbox end}}
