Notes: 1879: 114.6 @ 42. 2 measurements. It may be 80 times as big as the Sun. It is also an infra-red source. From James Kaler's Star Notes: Though possessed of a rather obscure name, Sadalmelik, the Alpha star of the constellation Aquarius (the Water Carrier), is hardly without its intrigue. The name, along with another star in the constellation, means "the lucky stars of the king or kingdom," the origin of the term quite lost to history. The star is unusual in several ways. It is classed as a type "G" modest supergiant, its surface temperature just a bit cooler than that of our 6,000 Kelvin Sun. Such "yellow supergiants" are relatively rare, however, most supergiants being either hot and blue or cooler and reddish. At a distance of 760 light years, we calculate Sadalmelik to have a luminosity 3,000 times that of the Sun, rendering it about 60 times the solar diameter, large, but nowhere near as large as the truly great supergiants that would fill the orbit of Jupiter. Its supergiant status tells us that it is highly evolved and dying. Yellow supergiants of this kind are commonly highly variable in brightness, of a type called a "Cepheid," named after the prototype, Delta Cephei. (Such stars indicate their luminosities by their periods of variability and are used to tell the distances of distant galaxies). Oddly Sadalmelik is not a Cepheid. Sadalmelik is also a rare "hybrid star." Less luminous stars of solar temperature tend to have magnetic fields that produce hot surrounding "coronas," the Sun's seen at the time of a solar eclipse. Very luminous stars, however, do not, instead having much cooler winds. Sadalmelik falls in between, with both characteristics. Observations: C8 at 104x.
