Science Highlights
The second quarter of 2013 delivered a number of significant papers based
on Gemini data. These include the three summarized here which feature
supernovae progenitor stars, stellar disks, and major results from the NICI
Planet-Finding Campaign. For an up-to-date list of scientific papers based on
Gemini data, see: http://gemininewpublications.blogspot.com/

Mass, Metallicity, and History of Supernova Progenitors
What are the progenitors of various types of supernovae? Spectral signatures and lightcurve
shapes characterize supernovae, and their range reveals the variety of progenitor stars that
may produce these events. Differences in progenitor mass, metal abundance, or multiplicity are all possible origins of supernova diversity. In recent work, Hanindy
