... Astronomers measure the brightness of stars at three colors of light: The "U" band at 360 nm The "B" band at 440 nm The "V" band at 540 nm The "color index" of a star is defined as the magnitude in the B filter, minus the magnitude in the V filter. Color Index = B-V, where B and V refer to the ...

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.
