2MASS J16003761−4835228 is a rare carbon-rich (and potentially metal-poor) symbiotic star (Miszalski & Mikołajewska, 2014). Notably, it exhibits the uncommon characteristic of a weak [Fe X] λ6375 Å emission line, coupled with a fairly strong Raman-scattered O VI emission band, placing it among symbiotic stars with the highest ionization levels, making it a good candidate for a supersoft X-ray source. However, the detection of soft X-rays in 2MASS J16003761−4835228 may be challenging due to potential obstruction by neutral gas and, to a lesser extent, dust in the Galactic plane.
