Star in the constellation Canis Major
Kappa Canis Majoris ,
Latinized from κ Canis Majoris, is a solitary,
[10] blue-white hued
star in the
constellation
Canis Major . It is visible to the naked eye with an
apparent visual magnitude of +3.87.
[2] Based upon an annual
parallax shift of 7.70
mas as seen from Earth,
[1] this star is located about 660
light years from the
Sun .
A
light curve for Kappa Canis Majoris. The main plot, from
Hipparcos data,
[11] shows the long-term variability and the inset plot, from
TESS data,
[12] shows the short-term variability.
This is a
B-type main-sequence star with a
stellar classification of B1.5 Ve,
[3] although Hiltner et al. (1969) classified it as B1.5 IVe
[13] suggesting it is a
subgiant star . The 'e' suffix indicates it is a rapidly rotating
Be star with a circumstellar
decretion disk of heated gas.
[7] The radius of the emitting disk is about ± 0.06
AU
[14] It is classified as a
Gamma Cassiopeiae type
variable star and its brightness varies from magnitude +3.4 to +3.97.
[3] The star became 50% brighter between 1963 and 1978, increasing from magnitude 3.96 or so to 3.52.

Naming In
Chinese , 弧矢 Hú Shǐ
Bow and Arrow ,
[16] refers to an asterism consisting of κ Canis Majoris,
δ Canis Majoris ,
η Canis Majoris ,
HD 63032 ,
HD 65456 ,
ο Puppis ,
k Puppis ,
ε Canis Majoris and
π Puppis . Consequently, κ Canis Majoris itself is known as 弧矢八 Hú Shǐ bā the Eighth Star of Bow and Arrow .)

Celestial Earth God's Temple asterism and ω Velorum is not member of any asterisms. 天社 (Tiān Shè) is westernized into Tseen She and R.H.Allen used the term Tseen She for Chinese name of
