Nuclei in the Cosmos (NIC) is a biennial series of Nuclear Astrophysics conferences. These interdisciplinary events gather together several hundred nuclear physicists, astrophysicists and cosmochemists, to review, share, and discuss recent advances (and challenges) in this field, covering broad areas, from the origin of the elements to the nuclear processes that power stars and their evolution. As such, it has become the most important international meeting in Nuclear Astrophysics.

With immense pleasure we announce the International "s, i & r Element Nucleosynthesis (sirEN)" Conference on the Nucleosynthesis of Heavy Elements.

This Conference is organised in the memory of Prof. Roberto Gallino, who recently passed away. We are honored to have worked with him and grateful for his genuine intelligence and friendship.

The BRIDGCE-IReNA 2025 annual meeting, hosted at the University of York, combines the fields of nuclear physics and astrophysics to highlight the latest interdisciplinary advancements in these fields, fostering knowledge exchange among BRIDGCE researchers and their partners from IReNA and ChETEC. This workshop offers early-career researchers and postdoctoral students a chance to present their research and engage in discussions with prominent researchers from the UK, US, and EU.

The BRIDGCE Explosive Nucleosynthesis Summer School will be held from Monday the 2nd of June to Tuesday the 3rd of June 2025 at the University of York. The school will introduce astrophysical transients and our current understanding of their nucleosynthesis through modelling, observations, and experimentation. With invited lecturers from within the BRIDGCE network and its collaborators, the school will focus on providing hands-on experience and creating opportunity for open discussions so that participants get the most from the experience.

The IReNA-CeNAM conference provides an engaging platform for researchers in nuclear physics and astrophysics to share their work, participate in professional development, and foster meaningful, lasting collaborations.

The Third Frontiers in Nuclear Astrophysics Summer School, hosted by Ohio University, is designed for early-career scientists in nuclear physics, astrophysics, and astronomy to strengthen their interdisciplinary expertise. Open to undergraduate students, graduate students, and postdocs, the program covers topics such as stellar evolution, nucleosynthesis, and state-of-the-art experimental and theoretical methods.

Abstract: The production of elements produced in stars is one of the main questions that is of critical interest in nuclear astrophysics. The majority of elements are traditionally produced via the slow (s) and rapid (r) processes.

Abstract: Nuclear reactions among charged particles in stars take place at energies generally well below the Coulomb barrier, so the Coulomb barrier penetration factor exponentially suppresses the cross sections down to values as small as few nanobarns or picobarns. Therefore, approaching astrophysical energies opens new challenges and calls for new approaches.

The 20th 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 16 (arrival and registration) to March 22 (departure) 2025.

The goal of this meeting is to discuss the uncertainties in calculating nuclear yields and the work needed to tie astrophysics observations to nuclear physics.  This 2-week meeting will both identify these uncertainties, fleshing out the details, driving further collaborations.  Topics include:

-nuclear cross-sections (including both theory, experiment)

-astrophysical trajectories (temperature, density, composition evolution with time)

-coupling nuclear to hydrodyanmics and thermodynamics

-nuclear networks

-astrophysical observations

This 61st edition of the Karpacz Winter School of Theoretical Physics is jointly organised by the Institute of Theoretical Physics and by the Institute of Astronomy, both of the University of Wroclaw (Poland), the Helmholtz-Centre Dresden-Rossendorf (Germany), the  Department of Physics and Astronomy of the University of Uppsala (Sweden) and the German Centre for Astrophysics in Görlitz (Germany)

Note: This seminar will take place 2:30pm-3:30pm Eastern Time

Depending on the reaction channel, direct determinations of neutron-induced reaction cross sections on stable and unstable isotopes for energies above 1 keV cross face different challenges. Neutron captures, neutron-induced fissions, charged-particle production reactions, elastic and inelastic scatterings are important and of interest for astrophysics and nuclear applications.

The interiors of neutron stars are inaccessible to direct observation. Measurements of gross properties- mass and radius- can help us constrain properties such as the dense matter equation of state, but provide little insight into properties such as composition, transport and magnetic fields. The electromagnetic emission from neutron star surfaces, magnetospheres and accretion disks is the primary way we are able to infer interior properties of neutron stars. This emission critically depends on the thermal and magnetic evolution of neutron stars.
