Notes
In the first arXiv version of the paper by Saeedi & Sasaki (2022), the star was considered as a symbiotic star candidate. However, it was later marked as "unclassified" due to uncertainty regarding whether a red giant is the companion. The star appears in the list of red giants in Tolstoy et al. (2001).
