Stellar nucleosynthesis is a vastly interdisciplinary field. There is a large number of different problems invoked calling for a variety of different and complementary research fields. Impressive progress has been made for the last decades in the various fields related to nucleosynthesis, especially in experimental and theoretical nuclear physics, as well as in ground-based or space...

The origin of elements from iron to uranium is considered to be one of the 11 greatest unanswered questions in physics published by the magazine Discover. Today, the rapid neutron-capture process of stellar nucleosynthesis is held responsible for their production. Although more sophisticated astrophysical models for the r-process have evolved in recent years, the astrophysical conditions for a...

JYFLTRAP is a double Penning trap at the Ion-Guide Isotope Separator On-Line (IGISOL) facility. A large variety of nuclei can be produced with the fast and chemically non-selective IGISOL method for JYFLTRAP experiments. Thus far, around 270 atomic masses have been measured with a typical precision of around 10 ppb.
In this contribution, mass measurements of isomeric states will be...

Neutron-deficient nuclei in the vicinity of the N = Z = 50 doubly-magic shell closure were produced at the National Superconducting Cyclotron Laboratory to study their structure and their relevance in the astrophysical rp-process. The 100Sn nucleus is the heaviest particle-stable N = Z nucleus, and it is also thought to be doubly magic. Additionally, 100Sn and its closest neighbours lie in the...

Observations of 60Fe are crucial for several astrophysical studies: (i) characteristic gamma-ray lines of 60Fe decay are observed in our galaxy confirming nucleosynthesis processes are still active nowadays, (ii) detection of 60Fe in marine sediment has been interpreted as a close-by supernova explosion 2 million years ago and (iii) observation of 60Fe in presolar grains is used to constraint...
