# Have any planetary systems been found around Population II stars?

I always understood that Population II stars were unlikely to have planets as they were virtually all H and He with very little else.

Have recent observations confirmed this, or have planets been discovered around Population II stars?

• Do you mean Population III stars? Population II stars do have lower metallicity than Population I, but they are by no means devoid of heavier elements.

• I seem to recall that below $[Fe/H] \approx -0.3$ stars count as Pop II, so that would include Kapteyn's star. Feb 26 '20 at 20:20
