To-scale sketch of the geometry for case #1, inferred for the GJ 486 planetary system based on our non-detection of SPIs at radio wavelengths. The system is viewed equator-on and has a low magnetic obliquity, meaning the magnetic dipole is aligned with the rotation axis (shown as a dot on the surface). The orbit of GJ 486 b is shown in blue, and the stellar magnetic field line connecting to the orbit is shown in red. The dashed lines on the stellar surface are lines of constant latitude, with the solid line showing the equator. We note that we found no bias toward any projected spin-orbit angle λ. For simplicity, we set λ = 0° here.
