Alshain
Beta Aquilae
Names For This Star
According to Allen, "Alshain" is derived from Persian name for Aquila, Shahin tara zed, "The Star-Striking Falcon." An alternative spelling is "Alschairn."
Description of the Star
Alshain is a binary star system. Alshain A is a yellow G8IV subgiant star about 5 times as luminous as the sun.
Alshain B is a red M3 dwarf. This star appears to be of 12th magnitude. From the spectral type, the star would have 40% of the diameter of the sun and an effective temperature of 3100 K. The dwarf would have about 1.5% of the luminosity of the sun and 30% of the sun's mass. (An apparent magnitude of 12 would imply 0.2% of the sun's luminosity.)
The observed separation of 13 seconds of arc between the components would correspond to a projected distance 180 AU, that is, about 4.5 times the radius of the solar system out to Pluto.
