This research uses astroseismology — the study of stellar vibrations — to probe the hidden interiors of stars. By analyzing oscillations in red giant stars, the work reveals information about stellar core masses and uncovers evidence of ancient stellar mergers. Listening to stars provides insights impossible to obtain through observation alone.

This research investigates “zombie stars” — reanimated white dwarf systems formed through stellar interactions in binary star systems. By analyzing large-scale brightness variations across the Milky Way, the work identified hundreds of these rare objects, providing new insights into stellar evolution, galactic history, and the future lifecycle of stars in our universe.
