Stars throw their weight in old galaxies
arXiv:1204.5888 · doi:10.1038/484462a
Abstract
The observation that old, massive galaxies have a larger fraction of low-mass stars than their younger, lower-mass counterparts adds to mounting evidence that star formation may have been different in the early Universe.
