Notes

Suspected of having a symbiotic nature by Akras (2023). The authors employed a combination of GALEX UV photometry, 2MASS/WISE IR photometry, and the ASAS-SN variables catalog to select the candidates. Their subsequent spectroscopic observations did not reveal any emission lines, leading to the suggestion that this star is an accreting-only symbiotic candidate.
