This Delta Scuti-type pulsating variable's infrared-radiating halo provided the first evidence for particulate ring growth outside the solar system. It is a bluish-white main sequence star whose B minus U and B minus V color indices are defined as zero. With Arcturus and Capella it divides the sky into thirds, and it forms the Summer Triangle with Deneb and Altair. Named from the Arabic for "swooping eagle," for 10 points, identify this star forecast to become a polestar by AD 14,000, the brightest star in Lyra and fifth brightest in the night sky.
