Notes. These parameters are explained in detail in Woitke et al. (2009) and Woitke et al. (2024). The two values of carbon-to-oxygen ratio corresponds to the canonical and the enhanced model, respectively. (a)The value for the luminosity differs from the reported value in Manara et al. (2017) as it is rescaled according to the new distance obtained from the Gaia 3 (Galli et al. 2021) release.
