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.
POSTPONED - Taking the Temperature: Statistical Nuclear Physics for Astrophysics and Applications (T3) (Opens in a new window)
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.

IReNA FA1 Stellar Burning Virtual Workshop Series (6/10, 6/17, 6/24, 7/1, 7/2) (Opens in a new window)
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.
As the 2020 R-matrix workshop on methods and applications has been postponed until 2021, we have put together a condensed online meeting via zoom for interested participants. A broad range of topics will still be covered, including both experimental and theory endeavors related to R-matrix. The online workshop will take place on Monday June 22, from 12:00 to 15:00 EST. There will be three one-hour sessions that will consist of a series of five to six short 5-minute talks, starting at the top of each hour.
This will be the tenth in a series of former JINA and now JINA-CEE meetings that brings together JINA-CEE participants, collaborators, and other interested researchers in nuclear physics, astronomy, and astrophysics to discuss progress and future directions related to the understanding of the origin of the elements and neutron stars.

FRIB offers unprecedented opportunities in nuclear astrophysics to understand element synthesis and compact stellar objects. Close collaboration between nuclear scientists and astrophysicists will be essential to develop the early experiment proposals that maximize the impact on the field. JINA-CEE has identified a number of astrophysicists that are interested in contributing to proposal development and would be available to help or to collaborate with nuclear theorists and experimentalists.
POSTPONED - International Workshop on Nuclear Statistical Physics in Astrophysics and Nuclear Applications (NuSPANA) (Opens in a new window)
We are organizing an international workshop on Nuclear Statistical Physics in Astrophysics and Nuclear Applications (NuSPANA). Nuclear reaction data is one of the key elements in nuclear applications ranging from simulating nucleosynthesis in stellar modeling to performance validation in nuclear energy and nuclear security. Experimental effort in the Los Alamos Neutron Science Center (LANSCE) is focused on neutron-induced reactions, in close collaboration with reaction theory development and continuous progress on cross-section evaluations at LANL.
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 15 (arrival and registration) to March 21 (departure) 2020. This school belongs to the European Network of Nuclear Astrophysics Schools (ENNAS). We shall limit the number of participants to about 60 to ensure a convivial atmosphere, and the possibility to share dinners between all participants.
IReNA Workshop - Progress on the reaction rates and stellar modelling affecting the 26Al abundance in the Galaxy (Opens in a new window)
The radioisotope 26Al is a key observable for providing information on the role of massive stars in the Galaxy as well as on the conditions in the early Solar System. It is produced in a number of astrophysical sites, from AGB stars and Wolf-Rayet winds through to novae and supernovae. To properly interpret the observational data, it is therefore crucial to understand to the production of 26Al in these different environments. There are a number of reactions which affect the final abundance of 26Al, including (but not limited to) 25Mg(p,g)26Al, 26Al(p,g)27Si, and 26Al(n,p/a).
The goal of this 3-day workshop is to launch the data interpretation phase of the RPA with selected experts in observational, theoretical and experimental r-process work.
The meeting will bring together experts from various fields to discuss the role played by lithium in several astrophysical contexts and to highlight the extraordinary character of this chemical species, as a tracer of the structure and evolution of stars, galaxies and the Universe.
The main topics of the meeting will be:
* Big Bang nucleosynthesis
* Nuclear reaction rates involving lithium and beryllium
* Physical processes in stellar interiors as traced by Li, Be, and B
* Hot bottom burning in massive AGB stars
Beyond iron, a small fraction of the total abundances in the Solar System is made of proton-rich isotopes, the p-nuclei. The clear understanding of their production is a fundamental challenge for nuclear astrophysics but still remains to be clarified.
Nuclear physics is the necessary link between astronomical observations, stellar models and galactic chemical evolution. The impressive progress in astrophysics during the last decades explaining and predicting astronomical scenarios was only possible because of the fruitful interplay between all disciplines. New insights in one field triggered new developments in the other fields. New experimental techniques are typically the response to new predictions and observations.
CEMP Stars as Probes of First-Star Nucleosynthesis, the IMF, and Galactic Assembly (Opens in a new window)
The beginning of the stellar era in the Universe is a singularly fascinating phase in the history of the Cosmos. The baryonic material filling the Universe at that time, having a composition inherited from Big Bang nucleosynthesis, has its physical characteristics modified by the very first stars. Indeed, the first stars will change the degree of ionized material in their vicinity, and, through their winds and/or supernova explosion, will inject energy, momentum, and newly-synthesized elements.
MICRA, which stands for Microphysics In Computational Relativistic Astrophysics, is a biennial workshop focused on improving, discussing, and addressing the microphysics needs of relativistic simulations of astrophysical systems, core-collapse supernovae, compact object mergers, and gamma-ray bursts by bringing together nuclear and neutrino theorists and astrophysicists and computational modelers. This year marks the 5th installment and the 10th anniversary of MICRA, and the first since the revolutionary gravitational wave event GW170817.
