Notes

This object is identified as a D-type symbiotic star based on its 2MASS colors. The continuum exhibits a weak and gradual rise, lacking the absorption bands characteristic of a red giant. Nonetheless, the confirmation of its genuine symbiotic nature is provided by the presence of Raman-scattered emission at 6825 Å (Corradi et al., 2010).
