This paper reviews the evidence for short–lived radionuclides in the early Solar System and critically evaluates models for their origin. Radionuclides with half–lives of less than 50 Myr for which firm and consistent evidence has been found are 10Be, 26Al, 41Ca, 53Mn, 60Fe, 107Pd, 129I and 182Hf. The oldest Solar System objects, calcium–aluminium–rich inclusions (CAIs), contained 10Be, 26Al, 41Ca and 53Mn on formation. We discuss whether a spallation or stellar origin for the radionuclides is…

Short-lived radionuclides (SLRs) are radioactive elements (T 1/2 ≺ 200 Myr) which were present in the nascent solar system and are now extinct. While the initial abundance of SLRs with the longest
The Origin of Short-lived Radionuclides and the Astrophysical Environment of Solar System Formation
Based on early solar system abundances of short-lived radionuclides (SRs), such as 26Al (T1/2 = 0.74 Myr) and 60Fe (T1/2 = 1.5 Myr), it is often asserted that the Sun was born in a large stellar
The Predictable Collateral Consequences of Nucleosynthesis by Spallation Reactions in the Early Solar System
Ever since their first discovery in 1960, the origin of the relatively short-lived radionuclides, now extinct but alive in the early solar system, has been under debate. Possible scenarios are either
Solar system genealogy revealed by extinct short-lived radionuclides in meteorites
Context. Little is known about the stellar environment and the genealogy of our solar system. Short-lived radionuclides (SLRs, mean lifetime τ shorter than 100 Myr) that were present in the solar
The radioactive isotope 60Fe (T1/2 = 1.5 Myr) was present in the early solar system. It is unlikely that it was injected directly into the nascent solar system by a single, nearby supernova (SN). It
High-precision measurements of heavy p-process isotopes in early solar system materials
This work investigates the abundances of rare, neutron poor isotopes of some heavy elements in meteorites. The elements in the solar system that are heavier than H and He were predominantly produced


Collateral consequences of the inhomogeneous distribution of short‐lived radionuclides in the solar nebula
Abstract— The presence of several short‐lived (now extinct) radionuclides in the early solar system demands that they were synthesized and added to preexisting solar system materials shortly (on a
Live Iron-60 in the Early Solar System
Isotopic analyses of nickel in samples from the differentiated meteorite Chervony Kut revealed the presence of relative excesses from the decay of the now extinct short-lived nuclide 60Fe, providing clear evidence for the existence of 60Fe over large scales in the early solar system.
Incorporation of short-lived (10)Be in a calcium-aluminum-rich inclusion from the allende meteorite
The particle fluence inferred from the initial beryLLium-10/beryllium-9 is sufficient to produce other short-lived nuclides, calcium-41 and manganese-53, found in meteorites, but the high canonical abundance of aluminum-26 may still require seeding of the solar system by radioactive stellar debris.
Short-Lived Radioactivities and the Birth of the sun
Now extinct short-lived radioactive isotopes were apparently extant in the early solar system. Their abundances can be inferred from isotopic effects in their daughter nuclei in primitive meteorites,
Short-lived radionuclide production by non-exploding Wolf-Rayet stars
This paper presents an extension and update of pre- vious calculations of the production by non-exploding Wolf- Rayet stars of radionuclides that could be responsible for cer- tain isotopic anomalies
Abundances of Actinides and Short-lived Nonactinides in the Interstellar Medium: Diverse Supernova Sources for the r-Processes
Abundances of 244Pu,235U,238U, and 232Th in the early solar system are about those expected for uniform production over most of galactic history. The inferred abundance of 182Hf is also compatible
Iodine-xenon dating
The most readily and widely studied of the extinct radionuclides in meteorites is I-129, and there is an extensive data base for meteorite chronology based on this isotope, but also significant
The rates of accretion, core formation and volatile loss in the early Solar System
Nuclides with half–lives of 105–108 yr permit the elucidation of nebula time–scales and the rates of accretion of planetesimals. However, the 182Hf–182W system with a half–life of 9_2 Myr also
The distribution of aluminum-26 in the early Solar System—A reappraisal
— A compilation of over 1500 Mg-isotopic analyses of Al-rich material from primitive solar system matter (meteorites) shows clearly that 26Al existed live in the early Solar System. Excesses of 26Mg
