Notes

ShWi5 exhibits a rich emission-line spectrum superimposed on a red stellar continuum. The 2MASS colors align with a D′-type symbiotic classification, further supported by the presence of a warm carbon-rich giant in the spectrum (equivalent to a late G-type). While there are no TiO bands, the spectrum displays the CH band and faint CN bands. The continuum is complemented by [Fe VII] emission, and the emission-line pattern is typical of D′-type symbiotics, as reported in Miszalski et al. (2013).
