Denebola shows a strong infrared excess , which most likely means there is a circumstellar debris disk of cool dust in orbit around it.  As the solar system is believed to have formed out of such a disk, Denebola and similar stars such as Vega and Beta Pictoris may be candidate locations for extrasolar planets . The dust surrounding Denebola has a temperature of about 120 K (−153 °C). Observations with the Herschel Space Observatory have provided resolved images, which show the disk to be located at a radius of 39 astronomical units from the star, or 39 times the distance from the Earth to the Sun. 
Denebadigege was used in the Alfonsine Tables ,  other variants include Deneb Adige , Denebedigege and Arided . This latter name was derived from Al Ridhādh , a name for the constellation. Johann Bayer called it Arrioph , derived from Aridf and Al Ridf , 'the hindmost' or Gallina . German poet and author Philippus Caesius termed it Os rosae , or Rosemund in German, or Uropygium – the parson's nose.  The names Arided and Aridif have fallen out of use.
