- 24_Aquilae abstract "24 Aquilae is the Flamsteed designation for a star in the equatorial constellation of Aquila. It is at a distance of around 410 light-years (130 parsecs) from Earth and has an apparent visual magnitude of 6.4. According to the Bortle Dark-Sky Scale, this star is just visible to the naked eye in dark rural skies.This is a so-called mild barium star, as identified by the mild presence of an absorption line of singly-ionized barium atoms at a wavelength of 455.4 nm. Such stars display an atmospheric overabundance of carbon and the heavy elements produced by the s-process, which was most likely transferred into the atmosphere by a wide binary stellar companion. However, in the case of 24 Aquilae, the abundances of heavy elements are near normal.At an estimated age of a half billion years, 24 Aquilae is a giant star with a stellar classification of K0 IIIa. It has more than double the mass of the Sun and shines with 63 times the Sun's luminosity. It is radiating this energy into space from its outer atmosphere at an effective temperature of 4,810 K. This heat is what gives it the cool orange hue characteristic of a K-type star.".
