Is our solar system weird; not all stars the same (Introduction)

The finding that our sun has a different sun spot pattern than another star creates another issue about our solar system. Our solar system probably needs our type of star which contains metals and the proper magnetic field:-https://www.sciencedaily.com/releases/2016/05/160504141125.htm-"A star like the Sun has an internal driving in the form of a magnetic field that can be seen on the surface as sunspots. Now astrophysicists from the Niels Bohr Institute have observed a distant star in the constellation Andromeda with a different positioning of sunspots and this indicates a magnetic field that is driven by completely different internal dynamics.-"What we can observe on the star is that it has a large sunspot at its north pole. We cannot see the south pole, but we can see sunspots at latitudes near the poles and these sunspots are not there at the same time, they are seen alternately on the northern and southern hemispheres. This asymmetry of sunspots indicates that the star's magnetic field is formed in a different way than the way it happens in the Sun," explains astrophysicist Heidi Korhonen.-***-"On the Sun, the sunspots appear and disappear on a regular basis and the number increases periodically approximately every 11 years. The magnetic field that creates the sunspots can also trigger large, explosive discharges of plasma, causing solar storms to hit the Earth. These storms result in very strong northern lights and can also cause problems for orbiting satellites and the power grid on Earth."-Comment: How special is our sun? I suspect we will find out.
