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.

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.

Sebastian Aguilar, University of Notre Dame

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.

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.

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).
