Massive (>10M_⊙) stars, which terminate their evolution as core collapse supernovae (CCSN), are theoretically predicted 1 to eject >10-5M_⊙ of the radioactive isotope 60Fe (half-life t1/2=(2.61±0.04) Ma; weighted average of Ref. 2 and 3). If suc

Supernova-produced 60Fe in Earth’s microfossil record

Autor: Ludwig, P., Bishop, S., Egli, R., Chernenko, V., Deneva, B., Faestermann, T., Fimiani, L., Gómez-Guzmán, J. M., Hain, K., Korschinek, G., Hanzlik, M., Merchel, S., Rugel, G.

It is possible for a nearby supernova (SN) explosion to deposit a fraction of its ejecta on Earth. Due to the lack of significant anthropogenic and cosmogenic background, 60Fe (T1/2 = 2.6 Ma) is perfectly suited to serve as a radioactive tracer of re

Search for supernova-60Fe in Earth’s microfossil record

Autor: Ludwig, P., Bishop, S., Egli, R., Chernenko, V., Deneva, B., Faestermann, T., Famulok, N., Fimiani, L., Guzman, J. M. G., Hain, K., Korschinek, G., Frederichs, T., Hanzlik, M., Rugel, G., Merchel, S.

Publikováno v: DPG-Frühjahrstagung der Sektion AMOP, 23.-27.03.2015, Heidelberg, Deutschland

Supernova (SN) explosions eject copious amounts of material into the interstellar medium. It is possible that supernova ejecta are incorporated into solar system reservoirs. 60Fe is an ideal isotope to search for such a signature, since it is produce

Material distributed into the interstellar medium by supernova explosions can be incorporated into terrestrial archives. After the discovery of live 60Fe atoms in 2-3 Myr old layers of a Pacifc Ocean ferromanganese crust (Knie et al., 2004), a confir

INTRODUCTION The radioisotope 60Fe (T1/2 = (2.62+0.04) Ma [1]) can be produced in copious amounts during different phases of evolution of massive stars. It is possible that 60Fe-rich supernova debris is deposited into solar system reservoirs [2]. Sam

Anomalous magnetic properties of brain tissue at low temperature: The 50 K anomaly

Autor: Hirt, A., Brem, F., Hanzlik, M., Faivre, D.

Publikováno v: Journal of Geophysical Research: Solid Earth

A low‐coercivity phase, identified as magnetite and/or maghemite, is the main iron oxide in brain tissue. Measurement of susceptibility as a function of temperature (χ–T) in brain tissue samples does not show a Verwey transition but instead show
