Extremely (54)Cr- and (50)Ti-rich presolar oxide grains in a primitive meteorite: Formation in rare types of supernovae and implications for the astrophysical context of solar system birth.

We report the identification of 19 presolar oxide grains from the Orgueil CI meteorite with substantial enrichments in (54)Cr, with (54)Cr/(52)Cr ratios ranging from 1.2 to 56 times the solar value. The most enriched grains also exhibit enrichments at mass 50, most likely due in part to (50)Ti, but...
