The Prompt Inventory from Very Massive Stars and Elemental Abundances in Ly Alpha Systems
Y. -Z. Qian, W. L. W. Sargent, G. J. Wasserburg
It has been proposed that very massive stars (VMSs) dominated heavy element production until a metallicity threshold corresponding to [Fe/H]=-3 was reached. This results in a promp…
