Research

My research focuses on binary star systems, where two stars orbit around each other. Specifically, I study cases where one of those stars is a neutron star, the densest type of star with the strongest gravitational pull in the universe. Combining observations from the newly-build MeerKAT radio telescope in South Africa with space-based telescopes detecting X-ray radiation, I investigate how and when such neutron stars attract the outer gas layers of their neighbor stars and eject some of that matter into surrounding space. Studying this process, we also aim to understand how these stellar binaries impact their interstellar environment by injecting it with matter and energy.
