This research investigates how exoplanets form by analyzing the chemical fingerprints of their host stars. Using stellar abundances and galactic archaeology, the work explores how rocky material shapes planetary systems, whether stars consume planets, and how common Earth-like worlds may be throughout the Milky Way.

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.
