Improved Mo neutron resonance parameters from neutron capture and transmission measurements at n_TOF and GELINA
R. Mucciola, S. Cristallo, S. Kopecky +140
We report high-resolution measurements of the cross section in the neutron energy range from a few eV up to about 250 keV, performe…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
Observational Signatures and Constraints on the Intermediate Neutron-Capture Process. The Case of the CEMP star TYC 6044-714-1 (RAVE J094921.8-161722)
Riano E. Giribaldi, Diego Vescovi, Laura Magrini +6
Observational abundances of CEMP stars with patterns in between those produced by the rapid and slow nucleosynthesis processes (CEMP-rs stars) are currently invoked as evidence of…
First Nb() Measurement: Constraining the Nucleosynthetic Origin of Mo in Presolar Grains
J. Balibrea-Correa, J. Lerendegui-Marco, C. Domingo-Pardo +136
Isotopic measurements of presolar silicon carbide grains from dying stars have revealed a puzzling overabundance of Mo that stellar nucleosynthesis models have failed to rep…
The MARTINI Platform (I): Se I-X atomic calculation and expansion opacity for early-stage kilonova spectral analysis
Matteo Bezmalinovich, Mattia Bulla, Gediminas Gaigalas +3
Kilonovae represent key sites of r-process nucleosynthesis, making opacity estimation and spectral analysis crucial for constraining their composition. Since light r-process elemen…
Impact of newly measured 26Al(n, p)26Mg and 26Al(n, α)23Na reaction rates on the nucleosynthesis of 26Al in stars
Umberto Battino, Claudia Lederer-Woods, Marco Pignatari +6
The cosmic production of the short-lived radioactive nuclide 26Al is crucial for our understanding of the evolution of stars and galaxies. However, simulations of the stellar sites…
