Notes.
is the effective stellar temperature,
denotes the stellar radius,
the gas mass-loss rate,
the dust condensation radius,
the terminal velocity of the wind, and
the turbulent velocity in the wind. The molecular fractional abundances are given relative to H
=n(H)+2n(H2), and denote the abundance at the dust condensation radius (see Fig. B.2).
Values between parentheses denote refined inner wind abundance values
obtained from the new HIFI observations.The fractional abundances for
all water isotopologs and isomers are based on the HIFI data presented
in this Letter.
