1The “inf” in the η column indicates that P in Equation (3.4) is very small, close to 0. When performing logarithmic calculations in Python, η approaches infinity and is therefore marked as “inf” in our results.
2Missing parameters are due to the interpolation sequence not providing the cooling age of ELM. The parameters of this ELM were calculated using the He-core model from Althaus et al. (2013). If we use the CO-core model from Bédard et al. (2020) for the calculation, the result obtained will be mass = 0.27 ± 0.03 M⊙ and agecool = 0.013 ± 0.013 Gyr. It is still an ELM.
