The star has a circumstellar disk despite being 3 billion years old. The infrared excess in the spectrum is consistent with two rings at different temperatures: an outer colder ring with a temperature of 480 K and an inner ring with a temperature between 550–1400 K. It may be a debris disk created from asteroids broken apart by the star's gravity.
