Dr. Poelarends and four Wheaton students (Scott Wurtz, (Physics '16), James Tarka, (Physics '15),  L. Cole Adams (Physics '13) and Spencer Hills (Physics '16 ) published a paper on Electron-Capture Supernovae in Close Binary Systems in the Astrophysical Journal in December, '17.

The paper presents the first detailed study of the Electron Capture Supernova Channel (ECSN Channel) for a primary star in a close binary star system. Poelarends used the  MESA stellar evolution code, to explore the parameter space of a range of  initial primary masses  using a large grid of models. They found that the initial primary mass and the mass transfer evolution are important factors in the final fate of stars in this mass range.
