- 71_Aquilae abstract "71 Aquilae is the Flamsteed designation for a binary star in the equatorial constellation of Aquila. It has the Bayer designation l Aquilae (l Aql). The apparent visual magnitude of the system is 4.33, making it bright enough to be viewed by the naked eye. It has an annual parallax shift of 9.67 mas, which equates to a physical distance of 340 light-years (100 parsecs) from Earth, give or take a 30 light-year margin of error. At this distance, the brightness of the system is diminished by 0.065 in visual magnitude from extinction caused by interstellar gas and dust.This is a spectroscopic binary system where the presence of an orbiting companion is revealed by shifts in the spectrum caused by the Doppler effect. The primary component is a giant star with a stellar classification of G8 III. The secondary is following a circular orbit with a period of 205.2 days.".
