Table 1.
Adopted model parameters associated with the two stars in the η Car system and their associated wind shocks.
| Parameter | η Car A | η Car B |
|---|---|---|
| R⋆ [R⊙] | 100 | 20 |
| T⋆ [K] | 2.58 × 104 | 3 × 104 |
| L⋆ [106 L⊙] | 4 | 0.3 |
| Ṁ [M⊙ yr−1] | 4.8 × 10−4 | 1.4 × 10−5 |
| v∞ [km s−1] | 5 × 102 | 3 × 103 |
| B⋆ [G] | 100 | 100 |
| vrot [v∞] | 0.15 | 0.15 |
| ηacc | 15 | 5 |
| Pp [Pwind] | 10% | 9% |
| Pe/Pp | 3% | 3% |
Notes. For T⋆, L⋆, Ṁ, and v∞ we used the same values as listed in Table 4, and for R⋆ the same values as in Table 1 of Parkin et al. (2009). 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 parameters adopted for our model (see text for details).
