Supergiant star, Achernar, has a high degree of flattening (1:1.5) see diagram. It has a dust ring like elliptical galaxies, and like the sun, its solar wind is emitted equatorially. See astrophysics paper 359,65-706 (2000)
Some B[e] supergiants have axial plasma ejection/s and circumstellar dust like their much larger elliptical galaxy counterparts.
Both the Earth and Saturn have similar torroidal magnetic fields and flat equatorial current flows. Probably all the planets are similar.
The sun’s electrical activity is highest at lower latitudes. Hence the poles are cooler. Evidence for a flat sun.
Saturn has an equatorial ring current of about 10,000,000 Amps flowing about 600,000 kilometres up. Kilometric Radiation is its principal radio emission.
