Elliptic flow from nuclear collisions is a hadronic observable sensitive to
the early stages of system evolution. We report first results on elliptic
flow of charged particles at midrapidity in Au + Au collisions at rootS(NN)
= 130 GeV using the STAR Time Projection Chamber at the Relativistic Heavy
Ion Collider. The elliptic flow signal, v(2), averaged over transverse mom
entum, reaches values of about 6% for relatively peripheral collisions and
decreases for the more central collisions. This can be interpreted as the o
bservation of a higher degree of thermalization than at lower collision ene
rgies. Pseudorapidity and transverse momentum dependence of elliptic how ar
e also presented.
