Title: Radioactive Nuclides in Outer Space

Abstract: Nuclear astrophysics is generally the study of the energy generation in stars and the origins of the chemical elements. In this highly multidisciplinary field, the job of experimental nuclear physicists is to constrain the nuclear reaction rates which are linked with astronomical observables. Observation of the lightest chemical element with no stable isotopes, technetium, in stellar spectra, was the first evidence that nucleosynthesis is an on-going process in our Galaxy.

This JINA-INT workshop will bring together researchers working on topics related to the thermal evolution of neutron stars, and transient and burst phenomena hosted by accreting and magnetized neutron stars.  

The hybrid meeting will involve a small group of in-person attendees at the Institute for Nuclear Theory at the University of Washington, and online participants from around the world. 

The Focus Area 1 (FA1) of the International Research Network for Nuclear Astrophysics (IReNA) is concerned with the determination of nuclear reaction rates of critical astrophysical importance in the laboratory using a broad range of experimental approaches, including heavy ion storage rings, deep underground laboratories, intense photon beams, neutron beams, and recoil separators at stable and rare isotope accelerator facilities.

We are excited to announce that the 2022 JINA-CEE Frontiers in Nuclear Astrophysics Meeting will take place on May 25-27, 2022 in South Bend, Indiana. Frontiers 2022 will also bring the IReNA community together in person for the first time.

Radioactive nuclei play a significant role in many current astrophysical pursuits, from the origin of the elements to the driving of emissions from supernovae ($^5$$^6$Ni) and kilonovae (r-process radioactivity). Radioactive nuclei are crucial for direct studies of galactic enrichment ($^7$Be, $^2$$^6$Al, $^4$$^4$Ti, $^6$$^0$Fe, $^9$$^9$Tc, $^2$$^4$$^4$Pu) and stellar explosions ($^5$$^6$Ni, $^4$$^4$Ti). Stars and their explosions, galaxies and their evolving interstellar medium, and the origin of the solar system are among the targeted astrophysical objects.
