Abstract

We run a three-dimensional Galactic chemical evolution (GCE) model to follow the propagation of ⁵³Mn (exclusively produced from type Ia supernovae, SNIa), ⁶⁰Fe (exclusively produced from core-collapse supernovae, CCSNe), ¹⁸²Hf (exclusively produced from intermediate mass stars, IMSs), and ²⁴⁴Pu (exclusively produced from neutron star mergers, NSMs). By comparing the predictions from our three-dimensional GCE model to recent detections of ⁵³Mn, ⁶⁰Fe, and ²⁴⁴Pu on the deep-sea floor, we draw conclusions about their propagation in the interstellar medium.

利用短寿命放射性同位素可以得出超新星激波传播的结论吗？

我们运行了一个三维银河化学演化（GCE）模型来跟踪53Mn（仅来自Ia型超新星SNIa）、60Fe（仅来自核心坍缩超新星CCSNe）、182Hf（仅来自中质量恒星IMSs）和244Pu（仅来自中子星合并nsm）的传播。通过将三维GCE模型的预测与最近在深海底探测到的53Mn， 60Fe和244Pu进行比较，我们得出了它们在星际介质中的传播结论。

期刊介绍： Astronomische Nachrichten, founded in 1821 by H. C. Schumacher, is the oldest astronomical journal worldwide still being published. Famous astronomical discoveries and important papers on astronomy and astrophysics published in more than 300 volumes of the journal give an outstanding representation of the progress of astronomical research over the last 180 years. Today, Astronomical Notes/ Astronomische Nachrichten publishes articles in the field of observational and theoretical astrophysics and related topics in solar-system and solar physics. Additional, papers on astronomical instrumentation ground-based and space-based as well as papers about numerical astrophysical techniques and supercomputer modelling are covered. Papers can be completed by short video sequences in the electronic version. Astronomical Notes/ Astronomische Nachrichten also publishes special issues of meeting proceedings.
