Earth is constantly bombarded with extraterrestrial dust containing invaluable information about extraterrestrial processes, such as structure formation by stellar explosions or nucleosynthesis, which could be traced back by long-lived radionuclides. Here, we report the very first detection of a recent ^{60}Fe influx onto Earth by analyzing 500 kg of snow from Antarctica by accelerator mass spectrometry. By the measurement of the cosmogenically produced radionuclide ^{53}Mn, an atomic ratio of…

60Fe deposition during the late Pleistocene and the Holocene echoes past supernova activity
The identified 60Fe influx may signal a late echo of some million-year-old supernovae with the 60Fe-bearing dust particles still permeating the interstellar medium.
Origin of Recent Interstellar 60Fe on Earth
Over the last 20 years, evidence for a 2 Myr old supernova 60 Fe influx onto Earth was provided by several authors. For the first time, independent investigations of samples from two different
60Fe and 244Pu deposited on Earth constrain the r-process yields of recent nearby supernovae
The plutonium content of a deep-sea crust sample was analyzed, identifying a few dozen atoms of the r-process isotope plutonium- 244 that were delivered to Earth within the past few million years and comparing the ratios constrains the relative contributions of supernovae and neutron star mergers to r- Process nucleosynthesis.
The quest for AMS of 182Hf – why poor gas gives pure beams
The long-lived radioisotope 182 Hf (T1/2 = 8.9 Ma) is of high astrophysical interest as its potential abundance in environmental archives would provide insight into recent r-process nucleosynthesis
53 Mn and 60 Fe in iron meteorites—New data, model calculations
We measured specific activities of the long‐lived cosmogenic radionuclides ⁶⁰Fe in 28 iron meteorites and ⁵³Mn in 41 iron meteorites. Accelerator mass spectrometry was applied at the 14 MV Heavy Ion
A nearby recent supernova that ejected the runaway star ζ Oph, the pulsar PSR B1706−16, and 60Fe found on Earth
The detection of ∼1.5–3.2 Myr old 60Fe on Earth indicates recent nearby core-collapse supernovae. For supernovae in multiple stars, the primary stars may become neutron stars, while former
The 59Fe (n,γ) 60Fe Cross Section from the Surrogate Ratio Method and Its Effect on the 60Fe Nucleosynthesis
The long-lived 60Fe (with a half-life of 2.62 Myr) is a crucial diagnostic of active nucleosynthesis in the Milky Way galaxy and in supernovae near the solar system. The neutron-capture reaction
New measurement of the Sm144(α,γ)Gd148 reaction rate for the γ process
Background: Most of the heavier $p$ isotopes are believed to be produced in the $\ensuremath{\gamma}$ process whose reaction path crucially depends on the proton and $\ensuremath{\alpha}$-particle
Rotational spectroscopy of rare iron monoxide isotopologues: A mass-independent analysis
We present pure rotational transitions of the rare iron monoxide isotopologues. , and in their lowest spin states . For , the rotational spectrum reveals hyperfine splitting due to the nuclear spin
Exploring the link between star and planet formation with Ariel
The goal of the Ariel space mission is to observe a large and diversified population of transiting planets around a range of host star types to collect information on their atmospheric composition.


Interstellar ^{60}Fe on the Surface of the Moon.
The concentration of the cosmic ray produced isotope ^{53}Mn, measured in the same samples, proves the supernova origin of the ^{60}Fe and deduces a reliable value for the local interstellar fluence in the range of 1×10^{8}  at/cm^{2}.
Indication for Supernova Produced 60 Fe Activity on Earth
In a deep ocean ferromanganese crust an excess of ${}^{60}\mathrm{Fe}$ radioactivity was measured by means of high sensitivity accelerator mass spectrometry. The enhanced concentrations measured in
Recent near-Earth supernovae probed by global deposition of interstellar radioactive 60Fe
The findings indicate multiple supernova and massive-star events during the last ten million years at distances of up to 100 parsecs, which indicates that a few per cent of fresh 60Fe was captured in dust and deposited on Earth.
Radioactive Iron Rain: Transporting $^{60}$Fe in Supernova Dust to the Ocean Floor
Several searches have found evidence of $^{60}$Fe deposition, presumably from a near-Earth supernova (SN), with concentrations that vary in different locations on Earth. This paper examines various
Cosmic ray exposure and pre-atmospheric size of the Gebel Kamil iron meteorite
Cosmogenic He, Ne, and Ar as well as the radionuclides 10Be, 26Al, 36Cl, 41Ca, 53Mn, and 60Fe have been determined on samples from the Gebel Kamil ungrouped Ni-rich iron meteorite by noble gas mass
An Update on Radiochemical Separation Techniques for the Determination of Long-Lived Radionuclides via Accelerator Mass Spectrometry
Long-lived radionuclides produced by cosmic rays in extraterrestrial matter not only preserve information about the irradiated objects themselves, e.g. meteorites, Moon or Mars, but they also give
60Fe anomaly in a deep-sea manganese crust and implications for a nearby supernova source.
A well resolved time profile of the 60Fe concentration in a deep-sea ferromanganese crust is measured and a highly significant increase 2.8 Myr ago is found.
Evidence for nearby supernova explosions.
It is proposed that approximately 2 Myr ago, one of the SNe exploded close enough to Earth to seriously damage the ozone layer, provoking or contributing to the Pliocene-Pleistocene boundary marine extinction.
Time-resolved 2-million-year-old supernova activity discovered in Earth’s microfossil record
A time-resolved 60Fe signal residing, at least partially, in a biogenic reservoir is reported through the direct detection of live 60Fe atoms contained within secondary iron oxides, among which are magnetofossils, the fossilized chains of magnetite crystals produced by magnetotactic bacteria.
Discovery of Jovian dust streams and interstellar grains by the Ulysses spacecraft
ON 8 February 1992, the Ulysses spacecraft flew by Jupiter at a distance of 5.4 AU from the Sun. During the encounter, the spacecraft was deflected into a new orbit, inclined at about 80° to the
