Sigma Octantis is a solitary [9] star in the Octans constellation that forms the pole star of the Southern Hemisphere.Its name is also written as σ Octantis, abbreviated as Sigma Oct or σ Oct, and it is officially named Polaris Australis (/ p oʊ ˈ l ɛər ɪ s ɔː ˈ s t r eɪ l ɪ s /). [10]
Kappa Velorum is a spectroscopic binary system consisting of a pair of stars that complete an orbit around each other with a period of 116.65 days and an eccentricity of 0.19. Because the individual stars have not been resolved, further details of the orbit have not yet been determined. [ 5 ]
It approved the name Prima Hyadum for the component Gamma Tauri A on 5 September 2017 and it is now so included in the List of IAU-approved Star Names. [ 13 ] In Chinese , 畢宿 ( Bì Xiù ), meaning Net , refers to an asterism consisting of Gamma Tauri, Epsilon Tauri , Delta³ Tauri , Delta¹ Tauri , Alpha Tauri ( Aldebaran ), 71 Tauri and ...
The two stars revolve each other along a circular orbit with the components separated by 12.9 times the Sun's radius. [3] Due to occultation of each component by the other, the apparent magnitude of the system decreased by 0.3 and 0.4 magnitudes over the course of the binary's orbit, which takes 34 hours 42.6 minutes to complete.
δ Cassiopeiae (Latinised to Delta Cassiopeiae) is the star's Bayer designation.WDS J01258+6014A is its designation in the Washington Double Star Catalog.. It also bore the traditional names Ruchbah and Ksora; the former deriving from the Arabic word ركبة rukbah meaning "knee", [9] and the latter appeared in a 1951 publication, Atlas Coeli (Skalnate Pleso Atlas of the Heavens) by Czech ...
