MHD simulation scenarios with corresponding key modelling parameters and resulting metastable He I absorption values.
| N | Bp (G) | mp (mJ) | Ṁsw (1011 g s−1) | Ṁp (1010 g s−1) | AHe I (%) |
|---|---|---|---|---|---|
| 1 | 0.01 | 0.002 | 1 | 2.9 | 1.24 |
| 2 | 0.5 | 0.1 | 1 | 1.5 | 0.74 |
| 3 | 1.0 | 0.2 | 1 | 0.9 | 0.57 |

Notes. The first column gives the number of the model run. Columns two and three list the equatorial planetary magnetic field strength in G and the magnetic moment in units of Jupiter magnetic moment. The fourth and fifth columns give the stellar wind and planetary mass-loss rates. The last column lists the total integrated metastable He I absorption in the ±10 km s−1 interval around 10 833.2 Å, following time averaging from −0.1 to +0.1 in planetary orbital phase. For these simulations, we considered a He/H abundance ratio of 0.01 (i.e. ten times less than that of the Sun).
