Award-winning publication: A large oxygen-dominated core from the seismic cartography of a pulsating white dwarf
Published in: Nature
The very first mapping of the inside of a white dwarf using asteroseismology techniques has revealed a stellar core that defies all predictions. Asteroseismology, a discipline that studies the deep oscillations from the interior of a star to its surface, provides a unique opportunity to discover a body's internal structure. White dwarfs are stellar cores of choice, since they are fossil stars that represent the final state of nearly 97% of the stars in our galaxy after a highly eventful evolutionary process. These advancements by Noemi Giammichele will help elucidate the physical mechanisms involved in the evolution of stars and the Sun.
