Editing Thorne–Żytkow object (section)

== Observation history ==

In 2014, a team led by [[Emily Levesque]] argued that the star [[HV 2112]] had unusually high abundances of elements such as [[molybdenum]], [[rubidium]], [[lithium]], and [[calcium]], and a high luminosity. Since both are expected characteristics of Thorne–Żytkow objects, this led the team to suggest that HV 2112 might be the first discovery of a TZO.<ref name=levesque/> However, this claim was challenged in a 2018 paper by [[Emma Beasor]] and collaborators,<ref name=beasor/> who argued that there is no evidence for HV 2112 having any unusual abundance patterns beyond a possible enrichment of lithium and that its luminosity is too low. They put forth another candidate, [[HV 11417]], based on an apparent over-abundance of rubidium and a similar luminosity as HV 2112.<ref name="beasor" />
