Study could uncover clues to the origins of powerful exploding stars
Supernovae are not just simply incredible explosions; they are a major source of elements in the interstellar medium and produce a shock wave that compresses gas clouds to aid new star formation. Supernova remnants might be a major source of cosmic rays. Despite a flurry of activities in the field, some key questions have not been adequately resolved. Funded by the Marie Skłodowska-Curie programme, the SNDTD project plans to determine the binary fraction of progenitors of core-collapse supernovae, which are fundamental in understanding the explosions. It will use integral field spectroscopy data and develop a new spectral synthesis model to resolve age distributions of stars formed around 10-200 million years ago.
