Short-lived Nuclei in the Early Solar System: Possible AGB Sources [PDF]
, 2005 (Abridged) We review abundances of short-lived nuclides in the early solar
system (ESS) and the methods used to determine them. We compare them to the
inventory for a uniform galactic production model.Abia, Abia, Alexander, Amari, Amari, Amelin, Amelin, Anders, Anders, Andric, Angulo, Argast, Arlandini, Audouze, Bao, Birck, Birck, Birck, Bizzarro, Black, Blake, Blander, Boothroyd, Boss, Brearley, Burbidge, Burnett, Busso, Busso, Busso, Cameron, Cameron, Cameron, Cameron, Cantelaube, Carlson, Cassen, Cayrel, Chakraborty, Charbonnel, Charbonnel, Chen, Chen, Chen, Chen, Chen, Chen, Chen, Chin, Choi, Choi, Choi, Clayton, Clayton, Clayton, Clayton, Connolly, Cowan, Cuzzi, Cuzzi, Dearborn, Denissenkov, Denissenkov, Desch, Diehl, Draine, Draine, Draine, Ebel, El Goresy, Feigelson, Formicola, Foster, Fowler, Fox, Frost, Frost, G.J.

, 2015 Carbon-rich grains with isotopic anomalies compared to the Sun are found in primitive meteorites. They were made by stars, and carry the original stellar nucleosynthesis signature.Fryer, C., Herwig, F., Hirschi, R., Hoppe, P., J. Jordan, C., K. Gibson, B., Pignatari, M., Trappitsch, R., X.

Hydrology, 2023 Accurate discharge measurement is mandatory for any hydrological study. While the “velocity” measurement method is adapted to laminar flows, the “dilution” method is more appropriate for turbulent streams.Antoine Picard, Florent Barbecot, Gérard Bardoux, Pierre Agrinier, Marina Gillon, José A.
