Intermediate-mass asymptotic giant branch stars and sources of Al, Fe, Pd, and Hf in the solar system

G. J. Wasserburg, Amanda I. Karakas, Maria Lugaro

We explore the possibility that the short-lived radionuclides Al, Fe, Pd, and Hf inferred to be present in the proto-solar cloud originated from $3-8…

Isotope Anomalies in the Fe-group Elements in Meteorites and Connection to Nucleosynthesis in AGB Stars

Gerald J. Wasserburg, Oscar Trippella, Maurizio Busso

We study the effects of neutron captures in AGB stars on \oq Fe-group\cqb elements, with an emphasis on Cr, Fe, and Ni. These elements show anomalies in Cr, Fe, and $…

Supernova-driven outflows and chemical evolution of dwarf spheroidal galaxies

Yong-Zhong Qian, Gerald J. Wasserburg

We present a general phenomenological model for the metallicity distribution (MD) in terms of [Fe/H] for dwarf spheroidal galaxies (dSphs). These galaxies appear to have stopped ac…

Chemical Evolution of the Juvenile Universe

G. J. Wasserburg, Y. -Z. Qian

Only massive stars contribute to the chemical evolution of the juvenile universe corresponding to [Fe/H]<-1.5. If Type II supernovae (SNe II) are the only relevant sources, then th…

Abundances in Metal-Poor Stars and Chemical Evolution of the Early Galaxy

G. J. Wasserburg, Y. -Z. Qian

We have attributed the elements from Sr through Ag in stars of low metallicities ([Fe/H] < -1.5) to charged-particle reactions (CPR) in neutrino-driven winds, which are associated…

Abundances of Sr, Y, and Zr in Metal-Poor Stars and Implications for Chemical Evolution in the Early Galaxy

Y. -Z. Qian, G. J. Wasserburg

Studies of nucleosynthesis in neutrino-driven winds from nascent neutron stars show that the elements from Sr through Ag with mass numbers A~88-110 are produced by charged-particle…
