Columba (Chinese Astronomy)
The modern constellation Columba lies across two of the quadrants, symbolized by the White Tiger of the West (西方白虎, ''Xī Fāng Bái Hǔ'') and the Vermillion Bird of the South (南方朱雀, ''Nán Fāng Zhū Què''), that divide the sky in traditional Chinese uranography. The name of the western constellation in modern Chinese is 天鴿座 (''tiān gē zuò''), meaning "the heaven dove constellation".

Columba (constellation)
Columba is a faint constellation designated in the late sixteenth century, remaining in official use, with its rigid limits set in the 20th century. Its name is Latin for dove. It takes up 1.31% of the southern celestial hemisphere and is just south of Canis Major and Lepus. History * Early 3rd century BC: Aratus's astronomical poem ''Phainomena'' (lines 367–370 and 384–385) mentions faint stars where Columba is now but does not fit any name or figure to them. * 2nd century AD: Ptolemy listed 48 constellations in the ''Almagest'' but did not mention Columba. * c. 150–215 AD: Clement of Alexandria wrote in his ''Logos Paidogogos''"Αἱ δὲ σφραγῖδες ἡμῖν ἔστων πελειὰς ἢ ἰχθὺς ἢ ναῦς οὐριοδρομοῦσα ἢ λύρα μουσική, ᾗ κέχρηται Πολυκράτης, ἢ ἄγκυρα ναυτική," (= " hen recommending symbols for Christians to use let our seals be a dove or a fish or a ship running in a good ...

Lambda Columbae
Lambda Columbae, Latinized from λ Columbae, is a probable binary star in the southern constellation of Columba. With an apparent visual magnitude of 4.86, it is faintly visible to the naked eye. The measured annual parallax shift of 9.75 mas yields an estimated distance of roughly 335 light years. Lambda Columbae has a stellar classification of B5 V, indicating that it is a B-type main sequence star. It is a suspected rotating ellipsoidal variable with a period of 0.64 days and an amplitude of 0.07 magnitude. Confirmation would indicate that this is a close binary system. It has an estimated age of around 57 million years. In Chinese, (), meaning ''Son A son is a male offspring; a boy or a man in relation to his parents. The female counterpart is a daughter.

Chinese Constellations
Traditional Chinese astronomy has a system of dividing the celestial sphere into asterisms or constellations, known as "officials" (Chinese ''xīng guān''). The Chinese asterisms are generally smaller than the constellations of Hellenistic tradition. The Song dynasty (13th-century) Suzhou planisphere shows a total of 283 asterisms, comprising a total of 1,565 individual stars. The asterisms are divided into four groups, the Twenty-Eight Mansions (, ''Èrshíbā Xiù'') along the ecliptic, and the Three Enclosures of the northern sky. The southern sky was added as a fifth group in the late Ming Dynasty based on European star charts, comprising an additional 23 asterisms. The Three Enclosures (, ''Sān Yuán'') include the Purple Forbidden Enclosure, which is centered on the north celestial pole and includes those stars which could be seen year-round,Needham, J.Astronomy in Ancient and Medieval China.

Delta Columbae
Delta Columbae is a binary star system in the constellation Columba. It can be seen with the naked eye having an apparent visual magnitude of 3.85. The distance to this system, based upon an annual parallax shift of 13.94 mas, is around 234 lightyears. Delta Columbae was a latter designation of 3 Canis Majoris, as the early astronomers Johann Bayer and John Flamsteed did not include the constellation Columba in their star charts. It has the uncommon traditional name Ghusn al Zaitun, from the Arabic الغصن الزيتون ''al-ghuşn al-zaitūn'' "the olive branch" (carried by the dove of Noah's Ark). This is a single-lined spectroscopic binary system with an orbital period of 868.78 days and an eccentricity of 0.7. It has a peculiar velocity of , making it a candidate runaway star system.

Kappa Columbae
Kappa Columbae, Latinized from κ Columbae, is a solitary star in the southern constellation of Columba. It has an apparent visual magnitude of 4.37, which is bright enough to be seen with the naked eye. Based upon an annual parallax shift of 17.87 mas, it is located at a distance of 183 light years from the Sun. It has a peculiar velocity of , making it a candidate runaway star. This is an evolved K-type giant star with a stellar classification of K0.5 IIIa. The measured angular diameter of this star, after correction for limb darkening, is . At the estimated distance of this star, this yields a physical size of about 10.5 times the radius of the Sun. It has an estimated 1.76 times the mass of the Sun and is about 1.7 billion years old. The star radiates 57.5 times the solar luminosity from its outer atmosphere at an effective temperature of 4,876 K. It is catalogued as a suspected variable star.

Gamma Columbae
Gamma Columbae, Latinized from γ Columbae, is a possible wide binary star system in the southern constellation of Columba. It is visible to the naked eye with an apparent visual magnitude of 4.36. Based upon an annual parallax shift of 3.75 mas, it is located roughly 870 light years from the Sun. The primary component is an evolved B-type subgiant star with a stellar classification of B2.5 IV.

Beta Columbae
Beta Columbae (β Columbae, abbreviated Beta Col, β Col), officially named Wazn , is the second-brightest star in the southern constellation of Columba. It has an apparent visual magnitude of 3.1, which is bright enough to be viewed with the naked eye even from an urban location. Parallax measurements place it at a distance of about from the Sun. Nomenclature ''Beta Columbae'' is the star's Bayer designation. It has the traditional name ''Wazn'' (or ''Wezn'') from the Arabic وزن "weight". In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN) to catalog and standardize proper names for stars. The WGSN's first bulletin of July 2016 included a table of the first two batches of names approved by the WGSN; which included ''Wazn'' for this star. In Chinese, (), meaning ''Son'', refers to an asterism consisting of Beta Columbae and Lambda Columbae. Consequently, Beta Columbae itself is known as (, en, the Second Star of Son.)

White Tiger (Chinese Constellation)
The White Tiger (Chinese: 白虎, Pinyin: ''Báihǔ''), known in Chinese as Baihu, is one of the Four Symbols of the Chinese constellations. It is sometimes called the White Tiger of the West (). It represents the west in terms of direction and the autumn season. It is known as Byakko in Japanese, Baekho in Korean, and Bạch Hổ in Vietnamese.
