Honing in on Supernova Origins
May 7, 2012
Type Ia supernovae are an important stellar phenomena used to measure the expansion of the universe. But astronomers know little about the stars they come from and how the explosions happen. But new research from a team led by Harvard University and including Carnegie's Josh Simon, Chris Burns, Nidia Morrell and Mark Phillips examined 23 Type Ia supernovae and helped identify the formation process for at least some of them.
The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering.
