WD growth of slowly dying ≤ M size stars fed by JPP comets is slower than the standard model SNe Ia events (see §2.3.1) where superwinds dump most of the mass of relatively short-lived 3 − 9M intermediate size stars into the ISM. Few SNe Ia events are seen at large redshifts, and this may be why. ...

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.
