The origin of nitrogen: Implications of recent measurements of N/O in Galactic metal-poor stars
C. Chiappini, F. Matteucci, S. K. Ballero
Recent new high-precision abundance data for Galactic halo stars suggest important primary nitrogen production in very metal-poor massive stars. Here, we compute a new model for th…
