HV 11417 is a candidate Thorne–Żytkow object, put forward in a paper by Emma Beasor and collaborators. The paper also claims that another candidate for the Thorne–Żytkow object, HV 2112, was not a Thorne–Żytkow object because it seemingly possessed no strange quality that would label it as a Thorne–Żytkow object.[1]
