Notes. For those works reporting a range of possible mass-loss rates, an intermediate value is provided for the ratio. For those works reporting a range of limits, the most conservative one is used as a reference for the ratio.
Obtained from Fig. 3 in Berger et al. (2023) for Te = 104 K and Te = 105 K, respectively, assuming Vs = 104 km/s. Valid for a CSM with a wind profile truncated at 2 × 1015 cm.
Derived in Smith et al. (2023).
