Notes. υLSR is the stellar velocity relative to the local standard of rest; T∗ is the stellar effective temperature; Rin is the dust condensation radius, taken to be the inner radius of the model; τ10 is the dust optical depth at 10 μm; Ṁ is the mass-loss rate; υ∞ is the gas terminal expansion velocity; β is the index of the radial velocity profile (see Eq. (1) of Maercker et al. 2016); RH2O is the e-folding radius of the Gaussian H2O radial abundance profile. All parameters are taken from Maercker et al. (2016).
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
