| '''HR 3803''' or '''N Velorum''' (N Vel) is a 3rd-[[Apparent magnitude|magnitude]] [[star]] on the border between the southern [[constellation]]s [[Carina (constellation)|Carina]] and [[Vela (constellation)|Vela]]. Based upon [[parallax]] measurements, it is approximately {{Convert|239|ly|pc|abbr=off|lk=on}} from [[Earth]]. It is an orange-hued [[stellar classification|K-type]] [[giant star]] and has twice the mass of the Sun.<ref name=aaa352_217/> The measured [[angular diameter]] of this star, after correction for [[limb darkening]], is {{nowrap|7.13 ± 0.08 [[milliarcsecond|mas]]}}.<ref name=aaa431_773/> At the estimated distance of Eta Draconis,<ref name=aaa474_2_653/> this yields a physical size of about 29 times the [[Solar radius|radius of the Sun]].<ref name=lang2006/>
| |
| | |
| In 1752, French astronomer [[Nicolas Louis de Lacaille]] divided the former constellation [[Argo Navis]] into three separate constellations, and then referenced its stars by extending [[Bayer designation|Bayer's system of star nomenclature]];<ref>http://homepage.mac.com/andjames/Page206.htm</ref> this star was given the designation ''N Velorum''. In 1871 [[Benjamin Apthorp Gould]] discovered this star to be [[variable star|variable]], but this occurred prior to the standardization of variable star nomenclature by German astronomer [[Friedrich Wilhelm Argelander]] during the nineteenth century, so it does not fall into the standard range of variable star designations.<ref name=jaavso16_2_65/>
| |
| | |
| The star should not be confused with [[HD 74272|n Velorum]].
