      Gamma-ray astronomy explores the most energetic photons in nature to address some of the most pressing puzzles in contemporary astrophysics. It encompasses a wide range of objects and phenomena: stars, supernovae, novae, ...

    • Iron-Group Abundances in the Metal-Poor Main Sequence Turnoff Star HD~84937 

      Sneden, Christopher; Cowan, John J.; Kobayashi, Chiaki; Pignatari, Marco; Lawler, James E.; Hartog, Elizabeth A. Den; Wood, Michael P. (2016-01-20)
      We have derived new very accurate abundances of the Fe-group elements Sc through Zn (Z = 21-30) in the bright main-sequence turnoff star HD 84937, based on high-resolution spectra covering the visible and ultraviolet ...

    • The RADIOSTAR Project

      Radioactive nuclei are the key to understanding the circumstances of the birth of our Sun because meteoritic analysis has proven that many of them were present at that time. Their origin, however, has been so far elusive. ...

    • Role of Core-collapse Supernovae in Explaining Solar System Abundances of p Nuclides 

      Travaglio, C.; Rauscher, T.; Heger, A.; Pignatari, Marco; West, C. (2018-02-07)
      The production of the heavy stable proton-rich isotopes between 74Se and 196Hg - the p nuclides - is due to the contribution from different nucleosynthesis processes, activated in different types of stars. Whereas these ...

    • S-process production in rotating massive stars at solar and low metallicities 

      Frischknecht, Urs; Hirschi, Raphael; Pignatari, Marco; Maeder, André; Meynet, George; Chiappini, Cristina; Thielemann, Friedrich Karl; Rauscher, Thomas; Georgy, Cyril; Ekström, Sylvia (2015-12-28)
      Rotation was shown to have a strong impact on the structure and light element nucleosynthesis in massive stars. In particular, models including rotation can reproduce the primary nitrogen observed in halo extremely metal ...
