Stellar and planetary parameters of some well known exoplanetary systems where SPMIs have been tentatively observed.
| Exoplanet name | R⋆ (R⊙) | P⋆ (days) | B⋆ (G) | Rp (RJ ) | Porb (days) | aorb (AU) | SCa–IIK (×1020 Watts) |
|---|---|---|---|---|---|---|---|
| HD 179949b | 1.23 | 11.0 | 3.2 | 1.22 | 3.0925 | 0.044 | 1.53 ± 0.27 |
| HD 189733b | 0.76 | 11.9 | 27.0 | 1.14 | 2.2186 | 0.031 | 0.28 ± 0.07 |
| τ Boo b | 1.48 | 3.7 | 2.6 | 1.13 | 3.3124 | 0.048 | 0.41 ± 0.11 |
| υ And b | 1.64 | 12.0 | 2.5 | 1.25 | 4.6170 | 0.059 | 1.14 ± 0.19 |
Notes. R⋆, P⋆, B⋆, Rp1, Porb and aorb represent the stellar radius, stellar rotation period, stellar magnetic field, the radius of the exoplanet, the orbital period of the exoplanet and the semi major axis of this orbit respectively. SCa–IIK represents the SPMI power observed in Ca-II K band. The values are as reported in Cauley et al. (2019) and have been used as input parameters in this work.
