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.

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 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.

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 aim of the conference is to bring together researchers interested in the significant role radioactive nuclei play in the cosmos and particularly with respect to questions in astrophysics.  The scientific program will cover topics related to the role of radioactivity within galactic chemical evolution, cosmochemistry, the origin of elements, and multi-messenger astronomy.
