'''HD 90132''' ('''HR 4086''') is a solitary,<ref name = Eggleton2008/> white hued [[star]] located in the southern [[constellation]] [[Antlia]]. It has an [[apparent magnitude]] of 5.33,<ref name = Tycho2000/> making it one of the brighter members of this generally faint constellation. The star is relatively close at a distance of 135 [[light year]]s<ref name = EDR3/> but is receding with a heliocentric [[radial velocity]] of {{val|17|ul=km/s}}.<ref name = Gontcharov2006/>

HD 90132 has a [[stellar classification]] of A8 V,<ref name = Houk1982/> indicating that it is an ordinary [[A-type main-sequence star]]. At present it has 1.69 times the [[mass of the Sun]] and 1.87 times the [[radius of the Sun]].<ref name = Stassun2019/> Despite a young age of 70 [[million years]],<ref name = Vican2012/> the star has a lower [[surface gravity]] than expected.<ref name = David2015/> This is due to the equator being 18% larger than poles,<ref name = "van Belle2012"/> all thanks to a high [[projected rotational velocity]] of {{val|270|ul=km/s}}.<ref name = Huang1953/> Nevertheless, it shines with a [[luminosity]] of {{val|9.8|ul=solar luminosity}}<ref name = GaiaDR2/> from its [[photosphere]] at an [[effective temperature]] of {{val|7737|ul=K|fmt=commas}}.<ref name = David2015/> HD 90132 is slightly metal deficient with a [[metallicity]] 74% that of [[Sun]].<ref name = Netopil2017/>

This star was observed for infrared excess suggesting the presence of a [[circumstellar disk]] but as of 2017, no excess have been found.<ref name = Meshkat2017/>

HD 90132 (HR 4086) is a solitary,[15] white hued star located in the southern constellation Antlia. It has an apparent magnitude of 5.33,[2] making it one of the brighter members of this generally faint constellation. The star is relatively close at a distance of 135 light years[1] but is receding with a heliocentric radial velocity of 17 km/s.[5]

HD 90132 has a stellar classification of A8 V,[3] indicating that it is an ordinary A-type main-sequence star. At present it has 1.69 times the mass of the Sun and 1.87 times the radius of the Sun.[7] Despite a young age of 70 million years,[12] the star has a lower surface gravity than expected.[9] This is due to the equator being 18% larger than poles,[16] all thanks to a high projected rotational velocity of 270 km/s.[11] Nevertheless, it shines with a luminosity of 9.8 L☉[8] from its photosphere at an effective temperature of 7,737 K.[9] HD 90132 is slightly metal deficient with a metallicity 74% that of Sun.[10]

This star was observed for infrared excess suggesting the presence of a circumstellar disk but as of 2017, no excess have been found.[17]
