Progress on nuclear reaction rates affecting the stellar production of ²⁶Al

Meynet, G.; Diehl, R.; Vink, J. S. +24 more

The radioisotope ²⁶Al is a key observable for nucleosynthesis in the Galaxy and the environment of the early Solar System. To properly interpret the large variety of astronomical and meteoritic data, it is crucial to understand both the nuclear reactions involved in the production of ²⁶Al in the relevant stellar sites and the…

Primordial black holes as a dark matter candidate

Kavanagh, Bradley J.; Green, Anne M.

The detection of gravitational waves from mergers of tens of Solar mass black hole binaries has led to a surge in interest in primordial black holes (PBHs) as a dark matter candidate. We aim to provide a (relatively) concise overview of the status of PBHs as a dark matter candidate, circa Summer 2020. First we review the formation of PBHs in the e…
