Andrew Steiner


Andrew Steiner has revisited this boundary in “Sound velocity bound and neutron stars,” published in Physical Review Letters. Paulo Bedaque from the University of Maryland is co-author on the paper, which was selected by PRL as an Editor’s Suggestion: one of a few publications recommended each week both for the interesting scientific results presented and successful communication across fields.

The paper describes how Steiner and Bedaque used the speed of sound to investigate the mysteries of matter at high density: one of the outstanding problems in nuclear and astrophysics. As Steiner explained, “the basic motivation [for looking at high-density matter] is that examining extreme forms of matter often gives us insight into what’s going on inside matter on earth. This is generally true: physicists are always looking at the hottest, coldest, densest, spinningest, lightest, heaviest, slowest, fastest, stickiest, or slipperiest things in order to try to figure out how stuff works.”
