Omega1 Aquilae

Omega¹ Aquilae (ω¹ Aquilae, ω¹ Aql) is the Bayer designation for a star in the equatorial constellation of Aquila. With an apparent visual magnitude of 5.2 it is a faint star that can be seen with the naked eye in dark skies. From the annual parallax shift of 7.86 mas, the distance to this star can be estimated as 410 light-years (130 parsecs), give or take a 20 light year margin of error.

The spectrum of this star fits a stellar classification of F0 IV. Typically, a luminosity class of IV means that the star is in the subgiant stage. It is rotating rapidly with a projected rotational velocity of 115  km/s. This is causing an equatorial bulge that is 5% larger than the polar radius.
