Eta Corvi

Eta Corvi is an F-type main-sequence star, the sixth-brightest star in the constellation of Corvus. It is located 59.5 light-years (18.2 parsecs) from the Sun based on its parallax. The star is faintly visible to the naked eye, at an apparent magnitude of +4.3. Two debris disks have been detected orbiting this star: a cold outer disk at ~150 AU, and a warm/hot inner disk within a few astronomical units (AU). The inner disk is notable for being brighter than expected, suggesting that it is replenished by materials from the outer disk.
