It has a very similar composition to the sun, just with more 'trace' elements. This gives us some benchmarks with which to contrast their behavior. More trace elements yields a shorter sunspot cycle. Our sun has about 99.9% Hydrogen and Helium (3:1) and about .1% other stuff. That gives us a solar cycle of about 11 years. The other star has .2% other stuff. That gives it a cycle of about 7.4 years. There is probably a formula for the cycle time where the cycle time decays exponentially with the amount of trace elements present.
I suspect that the higher metallicity of that star may indicate that the star is significantly younger than the Sun. Either that or some nearby supernovae popped off before the star was formed, since the supernovae and late stage large stars are the source of most metals.
Note: In stellar chemistry, anything bigger than helium is a “metal”.
