A Thorne–Żytkow object (TZO) is a hypothetical type of astronomical object that is a unique combination of a neutron star and a red giant star. This concept arises from theoretical studies in astrophysics and is named after physicists Kip Thorne and Edward Żytkow, who proposed the idea in the 1970s.
