Nuclear masses play a central role in nuclear astrophysics, significantly impacting the origin of the elements and observables used to constrain ultradense matter. A variety of techniques are available to meet this need, varying in their emphasis on precision and reach from stability. These are complemented by theory tools that identify key masses and extrapolate beyond experimental reach.

The third Nuclear Target Development Summer School (NTDSS2025) will be held at Texas A&M University (TAMU) in College Station, Texas, USA, from the afternoon of Friday, August 15 through lunchtime on Tuesday, August 19. The aim of the school is to excite and educate young researchers about the art and science of target making. Through these schools, the research community will be able to build the future workforce of target makers.

The HELIUM25 workshop aims to discuss the state of the art and future plans related to stellar helium burning. It will bring together the nuclear astrophysics community working on He-burning reactions. Various topics will be discussed, including direct and indirect measurements, the role of underground laboratories, detection methods, and astrophysical implications.

The school is a week-long event for students and postdoctoral researchers, combining elements of a traditional summer school with a hackathon. The primary goal of this summer school is to attract early career researchers (ECR) to the field of nuclear astrophysics, fostering a space for multidisciplinary collaboration within the IReNA network. The event will include a series of lectures introducing participants to a few of the major open questions in our field.

The 2nd IReNA-Ukakuren Joint Workshop “Advancing Nuclear Astrophysics and Beyond” will be held on 14th–18th July, 2025, at Osaka Metropolitan University (OMU) in Osaka.

A workshop to connect observational gravitational-wave astronomy with nuclear astrophysics. Our goal is to bring researchers from multiple fields together to understand how gravitational-wave astronomy will help us understand the dense matter equation of state and heavy-element nucleosynthesis in our universe.

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.

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

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.

In the context of our annual NuGrid collaboration meeting, we are hosting a half-day event with nuclear astrophysics talks, experimental and theoretical, open to the wider community. Our goal is to showcase recent results from the NuGrid collaboration and establish further connections and collaborations with interested groups.

Beyond iron, a number of rare, neutron-deficient, stable isotopes, is made of proton-rich isotopes, the p-nuclei. They constitute a small fraction in mass of the heavy nuclear species, but a clear understanding of their production still remains a fundamental challenge for nuclear astrophysics.
