New calculations by an international group of theorists paint a better picture of the nature of quark stars and suggest a way for astronomers to find the quark stars among the neutron stars. But WUSTL physicist Mark Alford, commenting on the journal publication in a news article posted Jan. 15 at PhysicsWorld.com, suggests that the new work may not be the last word. Alford, who uses mathematical modeling to explore the properties of quark stars, contends that the mathematical theory it uses is only truly accurate when the quarks are millions of times denser than they are in real neutron stars.

This could shed light on the behavior of neutron stars, above.Scientists have studied superconductors and superfluids for decades. Now, researchers at Washington University in St. Louis have drawn the first detailed picture of the way a superfluid influences the behavior of a superconductor. In addition to describing previously unknown superconductor behavior, these calculations could change scientists’ understanding of the motion of neutron stars.
