Notes

First known symbiotic star in IC10. The spectrum of the cool component well matches that of solar neighborhood M8 III giants. The observed emission lines belong to Balmer series, [S II], [N II] and [O III] (Gonçalves et al., 2008). They also noted that the spectrum of this system is an almost perfect copy of that of Hen 2-147, Galactic symbiotic star and Mira.
