Short-lived radioisotopes that can now only be traced through their daughter isotopes hold the key to many processes in the early solar system. In his Perspective, Zinner reviews recent attempts to elucidate these early events. Three main sources of short-lived isotopes are generally considered: the interstellar medium, high-energy particles from the early Sun, and a stellar event shortly preceding the formation of the solar system. The author argues that current evidence points to a… Expand
Short-lived nuclides in the early solar system: the stellar connection
Fossil evidence for the presence of short-lived nuclides with half-life ranging from 100,000 years to ~100 million years (Ma) in the early solar system has been found in primitive meteorites. TheExpand
Triggering the Formation of the Solar System
One of the most amazing discoveries in space science is the unambiguous evidence from meteorites that the solar nebula (the cloud of gas and dust in which the Sun and planets formed) containedExpand
The Irradiation Origin of Beryllium Radioisotopes and Other Short-lived Radionuclides
Two explanations exist for the short-lived radionuclides (T1/2 ≤ 5 Myr) present in the solar system when the calcium-aluminum-rich inclusions (CAIs) first formed. They originated either from theExpand
The astrophysical environment of the solar birthplace
Our Sun, like all stars, formed within a cold molecular cloud. Astronomical observations and theory provide considerable detail into this process. Yet cosmochemical observations of short-livedExpand
Vesta and Ceres: Crossing the History of the Solar System
The evolution of the Solar System can be schematically divided into three different phases: the Solar Nebula, the Primordial Solar System and the Modern Solar System. These three periods wereExpand
Nuclear Fossils in Stardust
In the 1950s, observation of the radioactive element technetium in stars led to the modern theory of nucleosynthesis that explains how elements are created. In his Perspective, [Nittler][1] discussesExpand
On early Solar System chronology: Implications of an heterogeneous spatial distribution of 26Al and 53Mn
Abstract Early Solar System chronology is usually built with the assumption that the distribution of short-lived radionuclides was homogeneous through the solar accretion disk. At present, there isExpand
SIMS analyses of Mg, Cr, and Ni isotopes in primitive meteorites and short-lived radionuclides in the early solar system
SIMS analyses of 26 Al- 26 Mg, 60 Fe- 60 Ni, and 53 Mn- 53 Cr systems in unequilibrated enstatite chondrites provide evidence for the former existence of 26 Al, 60 Fe, and 53 Mn in this highlyExpand
Superfluidity in the Solar Interior: Implications for Solar Eruptions and Climate
Efforts to understand unusual weather or abrupt changes in climate have been plagued by deficiencies of the standard solar model (SSM) [1]. Although it assumes that our primary source of energy beganExpand
Astrophysics in 2003
Five coherent sections appear this year, addressing solar physics, cosmology (with WMAP highlights), gamma-ray bursters (and their association with Type Ia supernovae), extra-solar-system planets,Expand

Did solar energetic particles produce the short-lived nuclides present in the early solar system?
Production of the short-lived nuclides 41Ca, 36Cl, 26Al, and 53Mn by solar energetic particles (SEP) interacting with dust grains of chondritic (\solar) composition is estimated considering a broadExpand
Short-Lived Nuclides in Hibonite Grains from Murchison: Evidence for Solar System Evolution
TLDR
Excess 10B that is found that is attributed to the decay of short-lived 10Be (half-life 1.5 million years) in hibonite grains from the Murchison meteorite is found and may rule out energetic particle irradiation as the primary source of41Ca and 26Al present in some early solar system solids and strengthens the case of a stellar source for 41Ca and26Al.

We carried out a theoretical evaluation of the contribution of Asymptotic Giant Branch (AGB) stars to some short-lived (10^6 ≤ τ ≤ 2 x 10^7 yr) isotopes in the ISM and in the early solar system usingExpand
The Solar System's First Clocks
Many insights into the formation of our solar system come from isotopic "clocks" in ancient primitive meteorites. But as [Gilmour][1] explains in his Perspective, gaining absolute dates for theseExpand

Incorporation of short-lived (10)Be in a calcium-aluminum-rich inclusion from the allende meteorite
TLDR
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.

Aluminum-26 in H4 chondrites: Implications for its production and its usefulness as a fine-scale chronometer for early solar system events
In order to investigate whether or not 26Al can be used as a fine-scale chronometer for early-solar-system events we measured, with an ion microprobe, Mg isotopes and Al/Mg ratios in separatedExpand

Lead Isotopic Ages of Chondrules and Calcium-Aluminum-Rich Inclusions
TLDR
The lead-lead isochron age of chondrules in the CR chondrite Acfer 059 is 4564.7 ± 0.6 million years ago, which indicates that CAI- and chondrule-forming events lasted for at least 1.3 My and supports the chronological significance of the 26Al-26Mg systematics. Expand
