Kivonat: 


Stellar explosions and colliding neutron stars are important nucleosynthesis 
sources. While some of the astrophysical processes responsible for element 
creation are well understood, others have remained elusive for decades. 
Processes creating elements often involve short lived radioactive isotopes 
that can be produced at accelerator facilities. Studies with these isotopes 
allow us to constrain the relevant nuclear reaction rates so one can 
understand in the laboratory how elements are created. 

In this talk, I will focus on the lighter heavy elements of the first 
r-process peak, between strontium and silver, and will review the important 
role that nuclear reactions play in understanding stellar explosions. I will 
discuss recent endeavours to experimentally constraint some of the relevant 
nuclear reaction rates and will emphasize the role of the newly commissioned 
SECAR (SEparator for CApture Reactions) recoil separator at the Facility for 
Rare Isotope Beams (FRIB) as well as new initiatives and plans for the 
future.
