摘要：

Establishing the origin of short-lived radionuclides (SRs) with half-lives similar to Ma has important consequences for the astrophysical context of our sun's birth place. I discuss here the different explanations that can account for the roster of SRs present in the solar accretion disk 4.57 Ga ago, emphasizing on their dependence on the poorly known initial value of SRs.
