Change in Bow Shock with Magnetic Field

If sigma_* and sigma_p are equal, the bow shock radius is unchanged with or without magnetic field - ratio of radius to orbital separation, chi_bow = 0.240468. With sigma_* = 1, sigma_p = 0.1, chi_bow = 0.148204; sigma_* = 0.5, sigma_p = 0.1, chi_bow = 0.187300; sigma_* = 0.1, sigma_p = 0.5, chi_bow = 0.302483; sigma_* = 0.1, sigma_p = 1, chi_bow = 0.363674; and with sigma_* = 0.5 and sigma_p = 1, chi_bow = 0.297793 ≈ chi_Coriolis.
