Abstract
The STAR detector has made a variety of measurements of strange and other hadronic species in Au+Au collisions at &surd;sNN &equal; 130 GeV. A comparison of kaon and pion production enables an examination of the systematics of strangeness production with energy by comparing them to lower energy collisions. Anti-baryon to baryon ratios indicate a much reduced net-baryon density and transverse momentum spectra show that a picture of transverse expansion seems appropriate.
