Star in the constellation Apus
HD 143346 (HR 5595 ) is a single
[14]
star in the southern
circumpolar constellation of
Apus . It is 28.5
minutes west and about 5° north of the
yellow giant star
Gamma Apodis , which is the second brightest star in the constellation of Apus.
This object has an orange hue and is visible to the naked eye as a dim point of light with an
apparent visual magnitude of 5.68
[2] It is located at a distance of approximately 286
light years from the
Sun based on
parallax ,
[1] and is drifting further away with a
radial velocity of 49
km/s . At that distance, the visual brightness of this star is diminished by an extinction of 0.174 due to
interstellar dust .
[3] The star has an
absolute magnitude of 0.95.
[7]
HD 1433456 has a
stellar classification of K1.5III CN1,
[4] indicating a
red giant that has an anomalous overabundance of
cyanogen in the
spectrum . It is currently on the
horizontal branch , generating fusion via a
helium
core . At present it has 118% the
mass of the Sun but has expanded to 10.6 times the
radius of the Sun .
[9] The star is radiating 53 times the
luminosity of the Sun
[1] from its
photosphere at an
effective temperature of 4,520
K .
[10] HD 1433456 is a member of the
Milky Way 's
thick disk ,
[15] but is metal enriched.
[3] It spins with a
projected rotational velocity lower than 1
km/s .
