Abstract

Trivedi's attempted disproof of presolar grains as carriers of special 129Xe* in meteorites is rejected on three grounds: (1) the high-T losses of 129Xe* and 1271 are tightly correlated, (2) the sharply isochronous meteorites are partially differentiated but not truly metamorphosed, and (3) evidence that much of solar 129Xe was trapped in presolar grains has strengthened the plausibility of the presolar-grain picture.
