Sorted by: Date Added To NTRS in Descending order Injection of freshly synthesized Ca-41 in the early solar nebula by an asymptotic giant branch star Author(s): Wasserburg, G. J.; Gallino, R.; Busso, M.; Goswami, J. N.; Raiteri, C. M. Abstract: We show that ejecta from the envelope of one asymptotic giant branch star of M is approximately 3 solar mass may account for many of the short-lived nuclei in the early solar system and also for the recent evidence of the ... NASA Center: NASA (non Center Specific) Publication Year: 1995 Added to NTRS: 2004-11-03 Accession Number: 95A74233; Document ID: 19950042634 AGB stars as a source of short-lived radioactive nuclei in the solar nebula Author(s): Wasserburg, G. J.; Gallino, R.; Busso, M.; Raiteri, C. M. Abstract: The purpose is to estimate the possible contribution of some short-lived nuclei to the early solar nebula from asymptotic giant branch (AGB) sources. Low mass (1 to 3 solar mass) AGB stars appear to provide a site for ... NASA Center: NASA (non Center Specific) Publication Year: 1993 Added to NTRS: 2004-11-03 Accession Number: 94N20859; Document ID: 19940016386 Asymptotic Giant Branch stars as a source of short-lived radioactive nuclei in the solar nebula Author(s): Wasserburg, G. J.; Busso, M.; Gallino, R.; Raiteri, C. M. Abstract: We carried out a theoretical evaluation of the contribution of Asymptotic Giant Branch (AGB) stars to some short-lived (10(exp 6) less than or equal to Tau-bar less than or equal to 2 x 10(exp 7) yr) isotopes in the ... NASA Center: NASA (non Center Specific) Publication Year: 1994 Added to NTRS: 2004-11-03 Accession Number: 95A66148; Document ID: 19950034549 Cool Bottom Processing on the AGB and Presolar Grain Compositions Author(s): Nollett, Kenneth M.; Busso, M.; Wasserburg, G. J. Abstract: We describe results from a model of cool bottom processing (CBP) in AGB (asymptotic giant branch) stars. We predict O, Al, C and N isotopic compositions of circumstellar grains. Measured compositions of mainstream SiC grains ...
