Notes. Due to a lack of literature data, the luminosity and effective temperature values flagged with asterisks (*) were calculated by us using the radiative transfer code More of DUSTY (Groenewegen 2012). The luminosities for U Ant, RZ Sgr, R Dor, and W Hya were scaled based on the results of the various works referenced in this table and the distances derived by Andriantsaralaza et al. (2022).
