Initially suspected in Pereira & Miranda (2005), subsequent analysis of high-resolution spectra by Miranda et al. (2010) confirms that this object is a strong candidate for a symbiotic binary system. A more recent study of Paunzen et al. (2023) suggests that the target comprises a hot central star surrounded by gaseous and dusty disks, an extended nebula, and the possibility of a companion star.
