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. 
Note the scales are a bit different, so that the habitable zones of the Sun and of HD 40307 line up better (remember, HD 40307g is actually closer to its star than Earth is to the Sun – an AU is the distance of the Earth to the Sun, so HD 40307 is about AU from its star). What makes me smile is that the new planet is actually better situated in its "Goldilocks Zone" than Earth is! That’s good news, actually: the orbit may be elliptical (the shape can’t be determined from the types of observations made) but still stay entirely in the star’s habitable zone.
Aquarius is a symbol of the giving of the Holy Spirit to God's people. Aquarius (Latin: pourer forth of water) shows a man pouring water from an urn into the mouth of a fish. The water represents the Holy Spirit (represented in Scripture as water or wind) and the fish represents God's people. The Holy Spirit was given at Pentecost fifty days after the resurrection of Jesus. This pouring of the Holy Spirit is referenced in Isaiah 44:3 "For I will pour water on the thirsty land, and streams on the dry ground; I will pour out my Spirit on your offspring, and my blessing on your descendants." The man in the constellation is called Hupei Tirion ("The Place of Him Coming Down" or "Poured Forth") . Associated decans (constellations) include: Piscis Austrinus (the Southern Fish), The Blessings Received. In Arabic, its name is Fom al Haut (The Mouth of the Fish). This decan is a fish with a wide open mouth into which flows water from Aquarius. This is a picture of the church receiving the blessings of the Holy Spirit. Pegasus (the Winged Horse), The Soon Return of the Redeemer. This decan is a winged horse. Peka or Pega means "Chief" and Sus means "Swiftly Coming". The stars in this constellation include Markab (Returning From Afar), Scheat (Who Carries), Enif (The Branch), Matar (Who Causes to Overflow with Joy). From the stars, we see the message that the Branch (Jesus) is swiftly returning from afar. This message is also given in Revelation 22:20: "Surely I come quickly" . (KJV) Cygnus (the Swan), The Sure Return of the Redeemer. This decan is pictured as a swan flying across the heavens. In both Greek and Latin its name means "circling" and "returning". In the zodiac of Dendereh, it was called Tesark (This From Afar). Stars include Deneb (The Lord Comes), Albireo (Flying Quickly), Sadr (Who Returns as in a Circle), Azel (Who Returns Quickly) and Fafage (Shining Forth). Summary of Associated Stars and Constellations
