abstract
Modern numerical simulations of the formation of the first stars predict that the first stars formed in multiples. In those cases, the chemical yields of multiple supernova explosions may have contributed to the formation of a next generation star. We match the chemical abundances of the oldest observed stars in the universe to a database of theoretical supernova models, to show that it is likely that the first stars formed from the ashes of two or more progenitors.

Coherent State Path Integral Reveals Unexpected Vacuum Structure in Thermal Field Theory
A coherent-state derivation of the thermal partition function yields extra vacuum and mass-coupling terms that the authors claim are novel, though these terms reflect the chosen operator ordering.
