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 [106L] 4 0.3
[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, , 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).
