: N. Giammichele et al. A large oxygen-dominated core from the seismic cartography of a pulsating white dwarf, Nature (2018). DOI: 10.1038/nature25136 Credit: University of Montreal

This week, Nature published an article that could challenge the theory of stellar evolution. “I think that, over the coming months, stellar astrophysicists will have to redo their calculations,” said Gilles Fontaine, a physics professor at Université de Montréal and one of the authors of the article, titled “A large oxygen-dominated core from the seismic cartography of a pulsating white dwarf.”

Its lead author is Noemi Giammichele, who completed her doctorate in 2016 under the joint supervision of Fontaine and his colleague Pierre Bergeron, both of whom co-authored the article along with 6 other researchers...
