Origin of the main r-process elements
The r-process is supposed to be a primary process which assembles heavy nuclei from a photo-dissociated nucleon gas. Hence, the reaction flow through light elements can be important as a constraint on the conditions for the r-process. We have studied the impact of di-neutron capture and the neutron-capture of light (Z 10) elements on r-process nucleosynthesis in three different environments: ne...
متن کاملR-process Pattern in the Very-metal-poor Halo Star Cs 31082-001
The very-metal-poor halo star CS 31082-001 was discovered to be very strongly r-process-enhanced during the course of a VLT+UVES high-resolution follow-up of metal-poor stars identified in the HK survey of Beers & colleagues. Both the strong n-capture element enhancement and the low carbon and nitrogen content of the star (reducing the CN molecular band contamination) led to the first U abundan...

متن کاملO / Fe in metal - poor main sequence and subgiant stars ⋆
A study of the O/Fe ratio in metal-poor main sequence and subgiant stars is presented using the [O i] 6300Å line, the O i 7774Å triplet, and a selection of weak Fe ii lines observed on high-resolution spectra acquired with the VLT UVES spectrograph. The [O i] line is detected in the spectra of 18 stars with −0.5 < [Fe/H] − 2.4, and the triplet is observed for 15 stars with [Fe/H] ranging from −...
متن کاملR-Process Abundances and Chronometers in Metal-Poor Stars
Rapid neutron-capture (i.e., r-process) nucleosynthesis calculations, employing internally consistent and physically realistic nuclear physics input (QRPA β-decay properties and the recent ETFSI-Q nuclear mass model), have been performed. These theoretical computations assume the classical waiting-point approximation of (n,γ) ← (γ,n) equilibrium. The calculations reproduce the solar isotopic r-...
