Alpha Sculptoris


Alpha Sculptoris (α Scl, α Sculptoris) is the Bayer designation for a star in the southern constellation of Sculptor. It has an apparent visual magnitude of +4.30,〔 which makes it the brightest star in this generally faint constellation. Parallax measurements collected during the Hipparcos mission provide a distance estimate for this star, placing it at roughly , with a 4% margin of error.〔
Alpha Sculptoris is a blue-white B-type giant. It is classified as an SX Arietis type variable star and its magnitude varies by 0.01.
The luminosity of α Scl is around 1700 times that of the Sun while its surface temperature is 14,000 kelvins. The radius of Alpha Sculptoris is calculated to be 7 times solar while its mass is 5.5 times that of our own star. Spectral variations observed in this star where once believed to be caused by an orbiting black hole but are now known to be the result of chemical variations in its atmosphere.
