The 18th Russbach School on Nuclear Astrophysics will take place in the village of Rußbach am Paß Gschütt, southeast of Salzburg, Austria. The school dates will be from March 12 (arrival and registration) to March 18 (departure) 2023.

This EMMI+IReNA Workshop will bring together experts from the four areas hydrodynamic simulations, neutrino-flavor physics, r-process nucleosynthesis, and kilonova modeling. The goal is to identify the main shortcomings of current models and to discuss strategies for how to propagate modeling uncertainties into r-process abundances and kilonova predictions, thereby improving models in a way to maximize the scientific output of future multi-messenger observations of neutron star mergers.

The school is connected to the International Conference on Nuclear Physics in Astrophysics X and aims at introducing important concepts related to nuclear astrophysics, including experimental and theoretical nuclear physics, astrophysics and astronomical observations.

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.

This summer school is intended to teach the application of stellar modelling using Modules for Experiments in Stellar Astrophysics (MESA) to those in the nuclear-astrophysics community and other interested researchers. Stellar modelling applications are becoming increasingly robust, and the availability of models for various stellar environments of interest to the nuclear-astrophysics community is constantly increasing.

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.

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 announce that the 17th Russbach School on Nuclear Astrophysics will again take place at the village of Rußbach am Paß Gschütt, southeast of Salzburg, Austria. The school dates will be from March 13 (arrival and registration) to March 19 (departure) 2022.

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 mission of CUWiP is to encourage undergraduate women to persist or start a career in physics by proving them with the opportunity to learn about career paths in physics, experience a professional conference, and discuss challenges and concerns. This conference was initiated in 2006 and research data indicate that CUWiP is effective in meeting its goals. It is being supported by in part from the National Science Foundation and the Department of Energy.

Our main goal is to connect researchers interested in the origin of isotopes working on presolar grain measurements, stellar chemical abundances, nucleosynthesis, and galactic chemical evolution to understand the origin of the isotopes. This will be a short two-half-day online workshop consisting of invited presentations. We will then organize a series of open online discussion sessions over the rest of the year on focused topics.

Nuclei in the Cosmos is the most important international meeting in the field of nuclear astrophysics. It brings together nuclear experimentalists, nuclear theorists, astronomers, theoretical astrophysicists, cosmo-chemists, and others interested in the scientific questions at the interface of nuclear physics and astrophysics. These questions concern, for example, the origin of the elements in the cosmos and the nuclear reactions that occur in the big bang, in stars, and in stellar explosions.

(α,n) reactions play a pivotal role in a variety of astrophysical sites and mass regions, and they can help us understand the origin of the elements. Their astrophysical rates are the main nuclear physics uncertainty in the weak r-process (also known as the α-process), which occurs in the neutrino driven ejecta of core-collapse supernovae and can explain the production of the lighter heavy elements, that are observed in metal poor stars. The 22Ne(α,n)25Mg and 13C(α,n)16O reactions are the main neutron sources for the s- and the i-processes.

Embracing the virtual nature of the workshop, the meeting will be broken into three half-day sessions. No parallel sessions are planned. Zoom will be used for the primary presentation of technical content, while substantial breaks are planned where critical informal discussion can take place in Gather.Town. Gather.Town allows us to invite you for a virtual coffee and exciting discussions.

Planned topics of discussion include:

We would like to invite you to participate in an online IReNA sponsored workshop on all things R-matrix that will be held from June 21 - 24, 2021. This meeting will have an abbreviated format and will focus on presentations by young and early career researchers.

The aim of this meeting is to bring together a diverse group of researchers with representatives from experiment and theory who utilize the R-matrix formalism for a variety of purposes.

Talks will span a wide range of topics covering experimental, theoretical, evaluation developments using R-matrix.

JINA-CEE and IReNA will organize “JINA Horizons” on November 30 - December 4, 2020 - a virtual meeting that brings together the international nuclear astrophysics community to discuss open questions and future directions.

The ChETEC COST Action (CA16117), the IReNA NSF network of networks, and the NuGrid collaboration are organising a 3-day training school event on the topic of nuclear reaction rates, stellar nucleosynthesis, observations and implications for galactic chemical evolution.

Statistical estimates of nuclear reaction rates are essential ingredients for astrophysical model calculations, e.g. r-process nucleosynthesis in neutron star mergers, and nuclear applications, e.g. next generation nuclear reactor performance. Rate calculations require experimental or theoretical constraints for nuclear properties such as level densities (temperature), gamma-strength functions, particle optical potentials, and level spin distributions.

Please join us on July 8th 2020 from 1:00-3:00 EDT for an online symposium to honor the late pioneer Eleanor Margaret Burbidge. This event will celebrate her life and science through short talks from her colleagues and collaborators as well as researchers who have benefited from her trailblazing and scientific insights.

Speakers include:
 

Megan Donahue - Michigan State University and past president of AAS

George Fuller - University California, San Diego

Anneila Sargent - California Institute of Technology

This virtual workshop is organized within FA1 and consists of a series of 4 seminars. The purpose is to build and strengthen international collaborations in nuclear astrophysics issues related to stellar burning (broadly defined). The structure will take advantage of the online format, taking place for 2-hour sessions each week for four weeks. The first hour of each session will consist of three 20-minute talks, while the second hour will be an open discussion.
