Presentation #104.04 in the session “An Exploration of Thorne-Zytkow Objects: TZOs, Theory and Candidates (Meeting-in-a-Meeting)”.
Levesque et al (2014, MNRAS, 443, 94) described the evidence that we had likely found the first identified Thorne-Zytkow object, HV 2112. In this talk, I will describe how this discovery came about, including the decades of work that laid the foundations for our work. I will also review the status of the star today: is it, or isn’t it, a TZO?
