Constraints on star systems: 1) Old enough to allow time for evolution (rules out high-mass stars - 1%) 2) Need to have stable orbits (might rule out binary/multiple star systems - 50%) 3) Size of “habitable zone”: region in which a planet of the right size could have ...

Corvus (constellation)
Corvus is a small constellation in the Southern Celestial Hemisphere. Its name comes from the Latin word ""raven"" or ""crow"". It includes only 11 stars with brighter than 4.02 magnitudes. One of the 48 constellations listed by the 2nd-century astronomer Ptolemy, it remains one of the 88 modern constellations. The four brightest stars, Gamma, Delta, Epsilon, and Beta Corvi from a distinctive quadrilateral in the night sky. The young star Eta Corvi has been found to have two debris disks.
