| '''Psi<sup>7</sup> Aurigae''' (ψ<sup>7</sup> Aur, ψ<sup>7</sup> Aurigae) is the [[Bayer designation]] for a single<ref name=mnras389_2_869/> [[star]] in the northern [[constellation]] of [[Auriga (constellation)|Auriga]]. It is a dim, naked eye star with an [[apparent visual magnitude]] of 5.02.<ref name=clpl4_99/> Based upon [[parallax]] measurements made during the [[Hipparcos]] mission,<ref name=aaa474_2_653/> it is approximately {{Convert|379|ly|pc|abbr=off|lk=on}} distant from [[Earth]].
| |
| | |
| This is an [[stellar evolution|evolved]] [[giant star]] with a [[stellar classification]] of K3 III.<ref name=apj116/> The measured [[angular diameter]] of this star, after correction for [[limb darkening]], is {{nowrap|1.96 ± 0.04 [[milliarcsecond|mas]]}}.<ref name=aaa431_773/> At it estimated distance,<ref name=aaa474_2_653/> this yields a physical size of about 24 times the [[Solar radius|radius of the Sun]].<ref name=lang2006/> The [[stellar atmosphere|outer envelope]] shines with an [[effective temperature]] of 4,300,<ref name=apjss74/> giving it the orange-hued glow of a [[K-type star]].<ref name=csiro/>
