Is There a way to Detect Strange Quark Stars, Even Though They Look Almost Exactly Like White Dwarfs?

The world we see around us is built around quarks. They form the nuclei of the atoms and molecules that comprise us and our world. While there are six types of quarks, regular matter contains only two: up quarks and down quarks. Protons contain two ups and a down, while neutrons contain two downs and an up. On Earth, the other four types are only seen when created in particle accelerators. But some of them could also appear naturally in dense objects such as neutron stars.

Um, quark stars, including strange quark stars, look almost exactly like neutron stars, rather than like white dwarfs.
An observation of the relationship between diameter and mass of neutron stars suffices to distinguish them.
