Studying the galactic chemical evolution with short lived radioisotopes (SLRs) has a significant advantage over using stable elements: Due to their radioactive decay, SLRs carry additional timing information on astrophysical nucleosynthesis sites.

We can use meteoritic abundance data in conjunction with a chemical evolution model to constrain the physical conditions in the last rapid...

67. 26Al: how to model a short-lived radioactive isotope - from a 1D to a 2D approach

$^{26}$Al is a short-lived radioactive nucleus ($\tau_{1/2}\,\sim$1 Myr) that can be used as a tracer of active star formation regions. In the past decades, observational data were collected in the Milky Way by $\gamma$-satellites as COMPTEL and INTEGRAL and I will show how we can reproduce them via chemical evolution models. The starting point is adopting a 1D chemical evolution model of the...
