Notes. Adapted from Table 1 in White et al. (2020). R⋆ denotes the stellar radius, T⋆ the surface temperature, L⋆ the luminosity, Ṁ the mass loss rate and v∞ the thermal velocity. The surface magnetic fields B⋆, the rotation velocities vrot, the acceleration efficiency parameters ηacc, the wind power going into the acceleration of protons Pp and the ratio Pe /Pp of the power going into the acceleration of electrons above 1 MeV and protons above 1 GeV were chosen in their model. For the photon field of η Car-A two different scenarios were assumed.
