Notes

This star exhibit a very rich, high-ionization emission-line spectrum with all the expected features, including Raman-scattered O VI 6825. The OGLE light curve conforms to the typical pattern for an S-type, featuring SR pulsations from the red giant and an orbital variation with a period of 854.5 days, as detailed in Miszalski et al. (2013).
