Table 6: Results for $\upsilon$ And b and HD 46375 b obtained with the Weber & Davis model with coronal temperatures T, magnetic field strengths B₀ and rotation periods $P_{\rm {rot}}$ as given as general parameters. For the two planets the radial and azimuthal velocity components $(v_r,v_\varphi )$ and the azimuthal magnetic field components $B_\varphi$ at the location of the planets are listed. With these, the magnetospheric stand-off distances $R_{\rm m}$ and magnetic moments ${\vec M}$ were estimated, followed by the power P that can be deposited by the stellar wind into the magnetosphere. For comparison the stand-off distance and the power input into the magnetosphere for the same planet located at 1 AU are also given.
